[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1An embodiment of the present invention proposes an electronic communication anti-interference system for information engineering, which generates transmission signals of multiple formats by copying the original signal, and uses the received transmission signals of multiple formats to merge and restore the original signal, so that even if part of the signal is interfered during the transmission process, it can be restored through signals of other formats, thereby improving the anti-interference ability.

[0032] The system of this embodiment specifically includes: a signal generation module, a diversified processing module, a signal transmission module and a signal processing module, wherein the signal processing module includes a signal receiving submodule, a demodulator, an analog-to-digital converter, and a digital signal processor; wherein,

[0033] The signal generation module is in communication with the diversification processing module, and is used to generate an original signal, pre-process the original signal, and copy the pre-processed original signal to generate multiple data blocks, and send them to the diversification processing module;

[0034] Specifically, the signal generation module is the starting point of the entire system. Its main task is to generate original signals and pre-process these original signals; pre-processing may include steps such as amplification and filtering to prepare for subsequent processing; the processed original signals will be copied into multiple data blocks, which will serve as the basis for generating signals in different formats; these data blocks are then sent to the diversified processing module for further processing.

[0035] The diversified processing module is in communication with the signal transmission module, and is used to encode and modulate the received multiple data blocks, generate transmission signals of different formats, and send them to the signal transmission module;

[0036] Specifically, the diversification processing module receives multiple data blocks from the signal generation module; for each data block, the module applies different coding schemes (such as convolutional codes, block codes, LDPC codes, etc.) and modulation techniques (such as QPSK, 16-QAM, etc.); the selection of these coding and modulation schemes depends on the channel characteristics and the expected interference type to ensure that the most appropriate combination is selected to improve the signal's anti-interference ability; after encoding and modulation, the diversification processing module generates transmission signals of different formats and sends these signals to the signal transmission module.

[0037] The signal transmission module is communicatively connected with the signal receiving submodule, and is used to convert the received transmission signals of different formats into corresponding high-power transmission signals, and send them to the signal receiving submodule;

[0038] Specifically, the signal transmission module receives signals of these different formats; in order to enhance the signal's anti-interference ability and transmission distance, the power amplifier in the signal transmission module will amplify the power of these signals; the signal transmission module will also select the most appropriate transmission path or frequency band to send each format of signal based on the channel characteristics and expected interference type; this can further reduce the possibility of signals being interfered with at the same time and improve the reliability of transmission.

[0039] The signal receiving submodule is communicatively connected to the demodulator, and is used to amplify the received multiple high-power transmission signals and send them to the demodulator;

[0040] The demodulator is communicatively connected to the analog-to-digital converter, and is used to perform preliminary processing such as demodulation and decoding on the received multiple amplified high-power transmission signals to recover the information of the multiple data blocks, generate corresponding analog signals in multiple formats, and send them to the analog-to-digital converter;

[0041] Specifically, when the signal transmission module sends high-power transmission signals to the receiving end, these signals are first captured by the receiving antenna; then, these signals are sent to the low-noise amplifier for amplification to maintain the signal-to-noise ratio; the amplified signals are then sent to the demodulator; the demodulator contains complex circuits and algorithms, which can demodulate the received signals; in this process, the demodulator will select the corresponding demodulation algorithm according to the modulation technology used by the transmitter (such as QPSK, 16-QAM, etc.) to restore the information of the original data block; for example, if the transmitter uses QPSK modulation technology, the demodulator will use the QPSK demodulation algorithm to process the received signal; through demodulation processing, the demodulator can generate analog signals in multiple formats, which are consistent in format with the original signals generated by the transmitter, but have been preliminarily restored and processed.

[0042] The analog-to-digital converter is communicatively connected to the digital signal processor, and is used to convert the received analog signals in the multiple formats into digital signals in corresponding multiple formats, and send the digital signals to the digital signal processor;

[0043] Specifically, the analog-to-digital converter (ADC) converts the amplitude values ​​of these analog signals into corresponding digital codes. This process is achieved through sampling and quantization. Sampling is to discretize the analog signal in time, while quantization is to convert the amplitude value of each sampling point into the closest digital value. After ADC conversion, the originally analog signals in multiple formats become corresponding digital signals. These digital signals have higher anti-interference capabilities and are easier to process in subsequent digital signals. Then, these digital signals will be sent to the digital signal processor (DSP) for further processing.

[0044] The digital signal processor is used to receive the digital signals in the multiple formats, and perform unified format conversion, signal alignment and deduplication, signal completion, signal merging and decoding processing on the digital signals in the multiple formats, so as to generate a complete original signal and output it.

[0045] For example, Figure 2 As shown, the system first generates the original signal through the signal generation module at the transmitting end; the original signal is amplified by the operational amplifier and pre-processed by the filter to remove unnecessary frequency components; the pre-processed signal is copied into multiple data blocks by the splitter to provide a basis for subsequent diversified processing; the diversified processing module receives multiple data blocks, and encodes and modulates each data block according to the preset coding scheme and modulation technology; the selection of coding and modulation schemes is aimed at improving the anti-interference ability of the signal and ensuring that the signal can be stably transmitted in different channel environments; after coding and modulation, transmission signals of different formats are generated; the signal transmission module receives transmission signals of different formats and transmits them through The time slot distributor transmits the signal to the corresponding power amplifier in time slot sequence; the power amplifier converts the transmission signal into a high-power transmission signal and sends it to the receiving end through the transmission antenna; the receiving end receives the high-power transmission signal of the corresponding format through the receiving antenna, and amplifies the signal through the low-noise amplifier; the amplified signal is sent to the demodulator for preliminary processing such as demodulation and decoding to restore the information of multiple data blocks; the analog-to-digital converter converts the analog signal into a digital signal; the digital signal processor receives digital signals in multiple formats, and performs unified format conversion, signal alignment and deduplication, signal completion, signal merging and decoding processing; finally, the complete original signal is generated and output.

[0046] Optionally, the signal generation module includes: a signal generator, an operational amplifier, a filter and a splitter; wherein,

[0047] The signal generator is communicatively connected with the operational amplifier, and is used to generate the original signal and send the original signal to the operational amplifier;

[0048] The operational amplifier is connected to the filter for amplifying the amplitude of the received original signal and sending the amplified original signal to the filter;

[0049] The filter is in communication with the splitter, and is used to pre-process the received original signal with amplified amplitude, remove unnecessary frequency components, and output the pre-processed signal;

[0050] The splitter is in communication connection with the diversified processing module, and is used for copying the pre-processed signal to generate the multiple data blocks, and sending the multiple data blocks to the diversified processing module.

[0051] For example, suppose an electronic communication task is being carried out, in which the signal generation module needs to generate a sine wave original signal with a frequency of 1kHz; the process is first started by the signal generator, which is responsible for generating this 1kHz sine wave original signal; this signal is a continuous waveform, and its amplitude, frequency and phase are precisely controlled; once generated, this original signal is sent to the operational amplifier; after the operational amplifier receives this original signal, the main task of the operational amplifier is to amplify the amplitude of the signal; assuming that the amplitude of the original signal is 1V, the operational amplifier may amplify it to 10V so that it has stronger anti-interference ability in subsequent transmission and processing; the amplified signal is then sent to the filter; the task of the filter is to pre-process the amplified signal and remove unnecessary frequency components; in this example, since it is desired to maintain a 1kHz sine wave signal, the filter Any spurious signals below or above this frequency will be removed; in this way, the pre-processed signal is a clean sine wave containing only 1kHz components, ready to be sent to the splitter; after receiving the pre-processed signal, the splitter will copy it into multiple data blocks; these data blocks are multiple copies of the signal, and each copy will be sent to the diversified processing module for different encoding and modulation processing; assuming that four data blocks are generated, then these four data blocks will represent the same 1kHz sine wave signal, but will be converted into four different transmission formats in subsequent processing; through this process, the signal generation module successfully generates an original signal and converts it into multiple data blocks through a series of pre-processing steps, preparing for subsequent diversified processing and transmission; the design of this module ensures the stability and anti-interference ability of the signal, providing a solid foundation for subsequent signal transmission and processing.

[0052] Optionally, the diversified processing module includes: an encoder, a modulator, and a multiplexer; wherein,

[0053] The encoder is communicatively connected to the splitter and is used to receive the multiple data blocks; the encoder is also communicatively connected to the modulator and is used to encode the multiple data blocks according to a preset encoding scheme and send them to the modulator;

[0054] The modulator is communicatively connected to the multiplexer, and is used to modulate the encoded multiple data blocks, generate the transmission signals in different formats, and send them to the multiplexer;

[0055] The multiplexer is communicatively connected with the signal transmission module, and is used to send the transmission signals of different formats to the signal transmission module through output channels of corresponding formats.

[0056] Exemplarily, assume that in the signal generation module, an original signal has been generated and preprocessed, and the signal is copied into four data blocks, which are marked as data blocks A, B, C and D respectively; the four data blocks are then sent to the diversified processing module for further processing; the encoder first receives the four data blocks; according to a preset coding scheme (for example, a convolutional code or a block code), the encoder encodes data block A to generate an encoded data block A'; similarly, the encoder also encodes data blocks B, C and D to generate encoded data blocks B', C' and D'; the encoded data blocks (A', B', C', D') are then sent to the modulator; the modulator receives the encoded data block A'; according to a preset modulation technique (for example, QPSK or 16-QAM), the modulator modulates the data block A' to generate a grid The transmission signal of formula 1; similarly, the modulator also modulates the data blocks B', C' and D', but may use different modulation techniques or parameters to generate transmission signals of format 2, format 3 and format 4; these transmission signals of different formats are then sent to the multiplexer; the multiplexer receives the transmission signals of format 1, format 2, format 3 and format 4; according to the needs of the signal transmission module or the preset transmission strategy, the multiplexer sends these transmission signals to the signal transmission module through the corresponding output channels; for example, the multiplexer may choose to send the transmission signals of format 1, format 2, format 3 and format 4 to four different channels; through such processing, the diversified processing module can generate transmission signals of various formats, which have different anti-interference characteristics, thereby improving the anti-interference ability of the entire electronic communication system. When the signal encounters interference during the transmission process, due to the use of transmission signals of various formats, the receiving end can more easily restore the original signal, thereby improving the reliability and stability of communication.

[0057] Optionally, the signal transmission module includes: a time slot allocator, a power amplifier and a transmission antenna; wherein,

[0058] The time slot distributor is connected in communication with the multiplexer and is used to receive the transmission signals of different formats; the time slot distributor is connected in communication with the power amplifier and is used to transmit the transmission signals of different formats to the corresponding power amplifier in time slot sequence;

[0059] The power amplifier is communicatively connected to the transmission antenna, and is used to convert the received transmission signals of different formats into corresponding high-power transmission signals, and send the high-power transmission signals to the transmission antenna;

[0060] The transmission antenna is communicatively connected to the signal receiving submodule, and is used to send the received corresponding high-power transmission signal to the signal receiving submodule.

[0061] Exemplarily, first, transmission signals of different formats (these signals may correspond to voice, video and data files, etc.) are sent to the time slot allocator; the time slot allocator carefully arranges the time period (i.e., time slot) for each signal transmission according to the priority of the signal and the channel status; this ensures that the signals will not interfere with each other and that channel resources can be used efficiently; these signals arranged in time slot sequence are sent to the power amplifier, which receives the signals from the time slot allocator and increases the power of these signals to a level sufficient to overcome various losses and interferences in the channel; in this way, even if the signal encounters attenuation or interference during transmission, it can still maintain sufficient strength so that it can be correctly received and decoded by the receiving end; finally, the high-power transmission signal that has been power amplified is sent to the transmission antenna; the transmission antenna transmits the received signal into the air in the form of electromagnetic waves; these electromagnetic waves carry information such as voice, video and data files, pass through the atmosphere and other possible obstacles, and finally reach the signal receiving submodule at the receiving end; through this specific example, we can see the importance of the signal transmission module in the electronic communication anti-interference system, which can not only ensure the stable transmission of the signal in a complex environment, but also effectively improve the signal's anti-interference ability and transmission efficiency through steps such as time slot allocation, power amplification and antenna transmission.

[0062] Optionally, the signal receiving submodule includes: a receiving antenna and a low noise amplifier; wherein,

[0063] The receiving antenna is connected to the transmitting antenna for receiving the high-power transmission signal of the corresponding format; the receiving antenna is also connected to the low-noise amplifier for sending the received high-power transmission signal to the low-noise amplifier; wherein the selection of the receiving antenna should match the transmission antenna of the transmitting end;

[0064] Specifically, the receiving antenna selects an antenna type that matches the transmitting antenna of the transmitting end to ensure that the high-power transmission signal of the corresponding format can be efficiently received; this matching may be based on the antenna's frequency range, polarization mode, gain and other characteristics; for example, if the transmitting end uses a circularly polarized antenna, the receiving end should also select a circularly polarized antenna to minimize signal loss.

[0065] The low noise amplifier is communicatively connected to the demodulator, and is used to amplify the received high-power transmission signal and send it to the demodulator.

[0066] For example, once the receiving antenna captures the signal, it immediately transmits the signal to the low-noise amplifier; the low-noise amplifier is a key component in the signal receiving submodule, and its main function is to amplify the received signal while minimizing the introduction of noise; this is because in the actual communication process, the signal will be interfered by various noises during the transmission process, such as thermal noise, interference signals, etc.; the low-noise amplifier can effectively improve the signal-to-noise ratio of the signal through its high-performance amplification characteristics, providing high-quality input for subsequent signal processing.

[0067] Alternatively, if Figure 3 As shown, the digital signal processor includes: a format conversion unit, an alignment and deduplication unit, a signal completion unit, and a merge decoding unit; wherein,

[0068] The format conversion unit is communicatively connected to the analog-to-digital converter and is used to receive the digital signals in the multiple formats; the format conversion unit is communicatively connected to the alignment deduplication unit and is used to convert the digital signals in the multiple formats into digital signals in a preset format and send them to the alignment deduplication unit;

[0069] For example, assume that the system receives digital signals in two formats: format A and format B; the format conversion unit first identifies the format information of the two signals, and then reorganizes the received data according to a preset algorithm or rule to generate a recombined signal; this recombined signal is data rearranged and combined according to a preset format (for example, format C); finally, the format conversion unit sends the generated digital signal in the preset format (format C) to the alignment deduplication unit for further processing.

[0070] The alignment and deduplication unit is communicatively connected with the signal completion unit, and is used to accurately align the received digital signal of the preset format and remove duplicate data blocks, thereby generating multiple basic signals and sending them to the signal completion unit;

[0071] Exemplarily, the alignment and deduplication unit receives a digital signal in a preset format from the format conversion unit, and performs precise alignment and deduplication processing; during the alignment process, the alignment and deduplication unit performs preliminary alignment based on the timestamp or synchronization information of the signal; then, the alignment algorithm is used to accurately align the preliminary aligned signal to ensure that each data block is in the correct position; in order to verify the accuracy of the alignment result, the alignment and deduplication unit will also calculate the alignment error and compare the similarity of adjacent data blocks; if an alignment error is found, precise alignment will be performed again; during the deduplication process, the alignment and deduplication unit will detect and remove duplicate data blocks; this is usually achieved by comparing data blocks in adjacent or same time periods; for duplicate data blocks, the alignment and deduplication unit will choose to retain the first one and delete other duplicate data blocks; in order to verify the accuracy of the deduplication result, the alignment and deduplication unit will also calculate the amount of data after deduplication and compare the data integrity before and after deduplication; after alignment and deduplication processing, the alignment and deduplication unit will generate multiple basic signals and send these signals to the signal completion unit for further processing.

[0072] The signal completion unit is communicatively connected to the merge decoding unit, and is used to complete the missing signal parts of the received multiple basic signals;

[0073] Exemplarily, the signal completion unit is responsible for completing the missing signal parts in the multiple received basic signals; during the completion process, the signal completion unit will first check the integrity of the data blocks of each basic signal; if a missing or damaged data block is found, it will be marked as a data block to be completed; then, the signal completion unit will identify the missing or damaged data block and confirm the starting and ending positions of the missing or damaged data segment or data packet; next, the signal completion unit will search and select the corresponding and complete data segment or data packet to be completed in other basic signals as the completion source; using this completion source, the signal completion unit will complete the data block to be completed; in order to verify the accuracy of the completion result, the signal completion unit will also perform an integrity check on the completed basic signal; if the completion result does not meet expectations, it will be re-completed; after the completion process, the signal completion unit will mark the basic signal that meets expectations as completed, and send these signals to the merge decoding unit for further processing.

[0074] The merging and decoding unit is used to merge the received multiple completed basic signals and perform final decoding processing to generate the complete original signal and output it.

[0075] Exemplarily, the merge decoding unit is the last processing link of the digital signal processor; its main task is to merge the received multiple completed basic signals and perform the final decoding process; during the merging process, the merge decoding unit will align the completed basic signals according to the timestamp and synchronization information of the signal; then, the signal merging algorithm is used to merge the aligned multiple basic signals to generate a complete signal; during the decoding process, the merge decoding unit will decode the merged signal to restore the original data information; the choice of decoding algorithm depends on the encoding scheme to ensure that the original signal can be correctly decoded; finally, the merge decoding unit will convert and reorganize the decoded signal to generate a complete original signal and output it; this original signal is the information that the system ultimately wants to transmit and can be used for subsequent processing or application.

[0076] Optionally, the format conversion unit includes:

[0077] identifying format information of each received digital signal;

[0078] reorganizing the received data according to the format information to generate a reorganized signal;

[0079] Converting the recombined signal into a digital signal in the preset format using a preset algorithm;

[0080] The generated digital signal in the preset format is sent to the alignment and deduplication unit.

[0081] For example, Figure 4As shown, it is assumed that the digital signal processor receives three digital signals of different formats from the analog-to-digital converter; these signals may use different encoding schemes or data structures, for example, the first signal is represented by a 16-bit integer, the second signal is represented by a 32-bit floating point number, and the third signal is in a custom binary format; the format conversion unit first identifies the format information of each received digital signal; this can be done by analyzing the header information, metadata, or specific identifiers of the signal; in this example, the format conversion unit identifies that the first signal is in a 16-bit integer format, the second signal is in a 32-bit floating point format, and the third signal is in a custom binary format; once the format of the signal is identified, the format conversion unit reorganizes the received data according to the format information; this may include parsing the data structure of the signal, extracting the valid data portion, and converting the data into a format that is easier to process; in this example, the format conversion unit converts each The data parts of the signals are extracted and prepared to be converted into digital signals of a preset format; next, the format conversion unit will use a preset algorithm to convert the reorganized signals into digital signals of a preset format; this preset format is usually a standard format defined within the system for subsequent signal processing; in this example, it is assumed that the preset format is a 32-bit floating point format; therefore, the format conversion unit will convert the first 16-bit integer signal into a 32-bit floating point format by extension or scaling, keep the second 32-bit floating point signal unchanged (or make necessary format adjustments to ensure consistency), and parse and re-encode the third custom binary format signal into a 32-bit floating point format; finally, the format conversion unit sends the generated digital signal of the preset format to the alignment and deduplication unit for further processing; in this example, the three digital signals of different formats have been successfully converted into the preset 32-bit floating point format and are ready for alignment and deduplication operations.

[0082] Optionally, the alignment deduplication unit includes:

[0083] Preliminarily aligning a plurality of digital signals in the preset format based on the timestamps of the signals;

[0084] Using an alignment algorithm to accurately align the preliminarily aligned multiple digital signals in the preset format;

[0085] The accuracy of the alignment result is verified by calculating the alignment error and comparing the similarity of adjacent data blocks. If the alignment is wrong, the alignment is re-performed accurately.

[0086] If the alignment is correct, duplicate data blocks are detected by comparing data blocks in adjacent or same time periods;

[0087] For repeated data blocks, the first one is selected to be retained, and other repeated data blocks are deleted, so as to generate a plurality of the basic signals;

[0088] By calculating the amount of data after deduplication, comparing the data integrity before and after deduplication, verifying the accuracy of the deduplication results, and re-deduplication if data is missing or wrong;

[0089] If the data is not lost, the basic signal is sent to the signal completion unit.

[0090] For example, Figure 5 As shown in the figure, the alignment deduplication unit will first perform preliminary alignment based on the timestamp of each digital signal. The timestamp is the time information attached to the signal when it is generated or transmitted, which is used to identify the sending or receiving time of the signal; by comparing the timestamps of different signals, the alignment deduplication unit can preliminarily sort and align the signals in chronological order; based on the preliminary alignment, the alignment deduplication unit will use more complex alignment algorithms (such as dynamic time warping, phase alignment, etc.) to accurately align the signals; these algorithms can take into account the slight differences between signals, such as time shift, phase offset, etc., to ensure that the signals are completely aligned in time; after the alignment is completed, the alignment deduplication unit will evaluate the accuracy of the alignment result by calculating the alignment error (such as mean square error, peak signal-to-noise ratio, etc.); at the same time, it will also compare the similarity of adjacent data blocks to further verify the reliability of the alignment result; if an alignment error or error is too large, the alignment deduplication unit will re-perform precise alignment until the predetermined alignment accuracy requirement is met; in the correctly aligned signal, the alignment deduplication unit will detect duplicate data blocks by comparing data blocks in adjacent or same time periods; since the signal may pass through different time periods during transmission, the alignment deduplication unit will detect duplicate data blocks by comparing data blocks in adjacent or same time periods; Different paths or different interferences may result in duplicate data blocks; the alignment deduplication unit will identify these duplicate data blocks and choose to keep the first one while deleting other duplicate data blocks; after deduplication is completed, the alignment deduplication unit will evaluate the accuracy of the deduplication result by calculating the amount of data after deduplication; at the same time, it will also compare the data integrity before and after deduplication to ensure that there is no data loss or error; if data loss or error is found, the alignment deduplication unit will re-perform deduplication processing until the predetermined data integrity requirements are met; after alignment and deduplication processing, the alignment deduplication unit will generate multiple basic signals; these basic signals are the signals after deduplication and alignment, and they will serve as the basis for subsequent signal completion and merge decoding; finally, the alignment deduplication unit will send these basic signals to the signal completion unit for further processing; through the above steps, the alignment deduplication unit can ensure that the multiple received digital signals are fully aligned in time and remove duplicate data blocks, thereby providing accurate and reliable basic signals for subsequent signal completion and merge decoding.

[0091] Optionally, the signal completion unit includes:

[0092] Performing integrity check on each data block of the basic signal;

[0093] Mark missing or damaged data blocks as data blocks to be completed;

[0094] Identify missing or damaged data blocks and confirm the start and end positions of missing or damaged data segments or data packets;

[0095] In the other basic signals, searching and selecting a complete data segment or data packet corresponding to the data block to be completed as a completion source;

[0096] Completing the data block to be completed using the completion source;

[0097] Performing an integrity check on the completed basic signal, and re-completing the basic signal whose completion result does not meet expectations;

[0098] The basic signal that meets expectations is marked as completed and sent to the merge decoding unit.

[0099] For example, Figure 6As shown, suppose that in a certain communication process, due to channel interference or transmission error, a data block (called data block A) in a certain basic signal received has some data missing; at this time, the signal completion unit will first check the integrity of all data blocks of this basic signal, find and mark data block A as the data block to be completed; next, the signal completion unit will carefully analyze data block A to determine the specific location and range of the missing data, that is, confirm the starting and ending positions of the missing data segment or data packet; this step is crucial for subsequent completion operations because it ensures the structural consistency of the completed data with the original data; then, the signal completion unit will search for a complete data segment or data packet corresponding to data block A in other basic signals; since the system adopts a diversified processing and data block replication strategy, it is likely to find a data block that is the same as data block A but complete in other basic signals; once such a data block is found, the signal completion unit will The full unit will use it as the completion source; using this completion source, the signal completion unit will complete the data block A to fill in the missing data; after completion, the signal completion unit will perform an integrity check on the data block A again to ensure the accuracy of the completion result; if the completion result meets expectations, that is, the data block A has been restored to a complete state, then the signal completion unit will mark it as completed and send it to the merged decoding unit together with other completed basic signals for subsequent processing; however, if the completion result does not meet expectations, such as the completed data block A still has errors or is missing, then the signal completion unit will re-perform the completion operation; this may include steps such as reselecting the completion source and adjusting the completion strategy until the expected completion result is obtained; through this process, the signal completion unit can effectively recover the data blocks missing due to channel interference or transmission errors, thereby improving the anti-interference ability of the communication system and the reliability of data transmission.

[0100] Optionally, the merge decoding unit includes:

[0101] Receiving all the completed basic signals;

[0102] Aligning all the completed basic signals according to the timestamps and synchronization information of the signals;

[0103] Using a signal merging algorithm to merge all of the multiple completed basic signals;

[0104] Decoding the combined signal;

[0105] The decoded signal is format converted and reassembled to generate the complete original signal and output it.

[0106] For example, Figure 7As shown in the figure, suppose that in a specific communication scenario, the system needs to transmit a high-definition video signal; this video signal is divided into multiple data blocks, and after being processed by encoding, modulation, etc., it is sent out in different formats; due to interference and noise in the channel, the signal received by the receiving end may be incomplete or erroneous; at this time, the merging and decoding unit is needed to play a role; first, the merging and decoding unit will receive all the completed basic signals; these basic signals have been processed by the signal completion unit, and the missing or damaged parts have been repaired; however, since there may be delays and jitters in the signal transmission process, these basic signals may not be aligned in time; therefore, the merging and decoding unit will accurately align these basic signals according to the timestamp and synchronization information of the signal; this step is crucial because only the aligned signals can be correctly merged and decoded; the alignment algorithm will take into account factors such as signal transmission delay and jitter to ensure that all basic signals are consistent in time; complete After alignment, the merge decoding unit will use the signal merging algorithm to merge multiple basic signals; the purpose of this step is to recombine the valid data scattered in multiple basic signals to form a complete signal; the signal merging algorithm needs to consider factors such as signal strength and phase to ensure the best quality of the merged signal; next, the merge decoding unit will decode the merged signal; the decoding process is the opposite of the encoding process, and it aims to restore the information in the original signal; the decoding algorithm will decode the merged signal bit by bit or block by block according to the encoding scheme to restore the content of the original signal; finally, the merge decoding unit will format convert and reorganize the decoded signal; since the original signal is divided into multiple data blocks before transmission and sent out in different formats, the decoded signal may need to undergo format conversion and reorganization to restore it to the original signal format; this step will ensure that the final output signal is completely consistent with the original signal, thereby meeting the requirements of the communication system.
