Description

Technical Field

[0001] The present invention relates to the field of mobile communication technology, and in particular to a new type of multi-frequency and multi-mode coverage system. Background Art

[0002] With the popularization of emerging technologies such as the Internet of Things (IoT), Vehicle-to-Everything (V2X) and smart cities, multi-band and multi-standard wireless communication systems have become the core supporting modern communication infrastructure. In order to meet the access requirements of different devices and different communication standards, how to efficiently process multi-band and multi-standard signals and improve the transmission efficiency and quality of the system has become an important issue in the communication field.

[0003] Currently, most traditional communication systems use a single standard or limited multi-standard signal processing solutions. Common wireless signal processing solutions such as frequency division multiplexing (FDM) and time division multiplexing (TDM) have certain limitations when supporting multiple communication standards. In addition, these solutions often need to rely on prior information of frequency bands and cannot dynamically adapt to the needs of different signal environments, which limits their flexibility and wide applicability.

[0004] Existing technical solutions still have shortcomings in practical applications, mainly manifested in the system's inability to adjust the interference between different signals in real time and adaptively, resulting in inaccurate signal amplification, energy waste and low processing efficiency. At the same time, since the traditional system has a relatively fixed signal processing process, it cannot flexibly respond to complex signal environments, especially in the dynamic switching of multi-mode and multi-band. The inflexibility of signal processing reduces the communication quality. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a new multi-frequency and multi-mode coverage system, which can identify and optimize the signal characteristics of different frequency bands and standards in real time by introducing a multi-dimensional signal feature adaptive dynamic enhancement mechanism, thereby significantly improving the signal processing efficiency and quality, so as to solve the deficiencies in the prior art in the above-mentioned background technology.

[0013] Preferably, the signal receiver is one of the core components in the system, responsible for receiving and filtering radio frequency signals in the frequency band of 700MHz to 5000MHz. The signal receiver is composed of receiving modules that support reception of multiple frequency band signals, and each module is specifically responsible for receiving signals in different frequency bands. The received radio frequency signal first enters the filter module to remove unnecessary frequency band signals and stray interference signals to ensure the purity of the transmitted signal. The filtered signal will be screened by the multi-dimensional signal feature adaptive dynamic enhancement mechanism. The system extracts multi-dimensional features of the signal through the multi-dimensional signal feature adaptive dynamic enhancement mechanism, including amplitude, phase and frequency, so as to identify and classify different types of signals.

[0014] Preferably, the envelope detection method based on signal energy is a technical method for extracting the envelope of a high-frequency modulated signal, that is, the change of the amplitude of the signal over time. For the 4G LTE of China Mobile, China Telecom, China Unicom and China Broadcasting Corporation, the four major domestic operators, the frequency bands that need to be analyzed for signal characteristics include: B1, B3, B5, B8, B34, B38, B39, B40, B41; for 5G NR, the frequency bands that need to be analyzed for signal characteristics include: N1, N5, N8, N28, N41, N77, N78, N79.

[0015] Preferably, the 4G LTE supports different carrier bandwidth configurations, which can be configured as: 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, 20MHz, etc. according to the 3GPP specification; but in actual commercial use, the main typical bandwidth configurations are: 10MHz, 15MHz, 20MHz; 5G NR supports different carrier bandwidth configurations, which can be configured as: 5MHz, 10MHz, 15MHz, 20MHz, 30MHz, 50MHz, 60MHz, 80MHz and 100MHz according to the 3GPP specification; in scenarios not involving carrier aggregation, 100MHz is the most typical bandwidth configuration of the 5GNR; but in actual commercial use, the main typical bandwidth configurations are: 100MHz, 50MHz, etc.; therefore, in the envelope detection processing based on signal energy, the typical bandwidth configurations can be detected and processed first.

[0016] Preferably, the envelope detection method based on signal energy adopts a fast detection method based on a combination of frequency band and frequency point number, including 4G and 5G detection methods, wherein the specific method and steps of the 4G are: the S1 is to first detect the signal from the B1 frequency band, based on the commonly used frequency point numbers 1 to N, set the characteristic frequency point number, take the frequency corresponding to the frequency point number as the center frequency, and detect the signal energy of 10MHz, 15MHz, and 20MHz bandwidths in turn, which are recorded as: P 10MHz , P 15MHz , P 20MHz When P 10MHz , P 15MHz , P 20MHz If the frequency point is lower than the threshold value TH0, there is no valid signal at this frequency point. 10MHz , P 15MHz , P 20MHz If the value is higher than the threshold value TH0, then there is a useful signal at the frequency point number; the specific operation is as follows: when P in S11 10MHz , P 15MHz , P 20MHz shows a significant increase, the signal bandwidth corresponding to the frequency point number is 20MHz; when P in S12 10MHz , P 15MHz There was a significant increase in P 15MHz , P 20MHz The increase is not significant, so it can be judged that the signal bandwidth corresponding to the frequency point number is 15MHz, and the energy superposition from 15MHz to 20MHz is noise; when P in S13 10MHz , P 15MHz , P 20MHzIt shows an insignificant increase, and it can be judged that the signal bandwidth corresponding to the frequency point number is 10MHz, and the energy superposition noise from 10MHz to 15MHz and 15MHz to 20MHz; the S14 records the B1 frequency band and the effective bandwidth of the signal under the frequency point number; the S2 then uses the processing method of S1 for other frequency points in the B1 frequency band until the processing of N frequency points in the B1 frequency band is completed; the S3 then uses the processing methods of S1 and S2 for the B3 frequency band to record the corresponding frequency band information, frequency point number information and bandwidth information; the S4 processes B5, B8, B34, B38, B39, B40 and B41 in turn, uses the processing methods of S1 and S2 to record the corresponding frequency band information, frequency point number information and bandwidth information;

[0017] Preferably, the specific method and steps of 5G are: W1 first detects the signal from the N1 frequency band, sets the characteristic frequency number based on the commonly used frequency point numbers 1 to M, takes the frequency corresponding to the frequency point number as the center frequency, and detects the signal energy of 50MHz and 100MHz0 bandwidth in turn, which are recorded as: P 50MHz , P 100MHz ; When, P 100MHz If the frequency point is lower than the threshold value TH1, there is no valid signal at this frequency point. 50MHz , P 100MHz If the value is higher than the threshold value TH1, then there is a useful signal at the frequency point number. The specific operation is as follows: when the P in W11 50MHz , P 100MHz shows a significant increase, the signal bandwidth corresponding to the frequency point number is 100MHz; when P in W12 50MHz , P 100MHz It shows an insignificant increase, so it can be judged that the signal bandwidth corresponding to the frequency point number is 50MHz, and the energy superposition from 50MHz to 100MHz is noise; then the W13 records the effective bandwidth of the signal under the N1 frequency band and the frequency point number; the W2 then uses the processing method of W1 for other frequency points in the N1 frequency band until the processing of the M frequency points in the N1 frequency band is completed; the W3 then uses the processing methods of W1 and W2 for the N5 frequency band to record the corresponding frequency band information, frequency point number information and bandwidth information; the W4 processes N8, N28, N41, N77, N78 and N79 in turn, uses the processing methods of W1 and W2 to record the corresponding frequency band information, frequency point number information and bandwidth information;

[0018] Preferably, the signal feature analysis module also includes an adaptive dynamic enhancement mechanism, which optimizes the signal feature recognition process in real time through frequency clustering and time series analysis to improve signal recognition accuracy. The frequency clustering unit is responsible for separating signal features from different communication standards and frequency bands in real time to avoid mutual interference between signals; the time series analysis unit dynamically optimizes the signal feature extraction and classification process based on historical data and real-time changing signal environment. By introducing these algorithms, the system can adaptively process different types of signals and improve signal recognition and classification accuracy in complex environments. For example, the system can automatically detect and adjust signal classification strategies to adapt to dynamic changes in parameters such as signal frequency, bandwidth, and number of carriers, thereby ensuring efficient signal processing.

[0019] Preferably, after the uplink and downlink signal processing circuit receives the signal characteristic information from the signal characteristic analysis module, the signal detection unit first performs a validity detection on the received signal. The signal is considered valid only when it meets the set signal quality standard, such as RSSI is greater than a preset threshold. The valid signal will be targetedly filtered by the filter to remove unnecessary frequency components. Subsequently, the gain adjuster dynamically adjusts the amplification factor according to the signal characteristic information to ensure the optimal effect of signal amplification. The amplifier then amplifies the filtered signal to prepare for signal transmission to the target area. The design of the uplink and downlink signal processing circuit can avoid blind amplification of the entire frequency band, reduce system energy waste, and improve signal transmission efficiency.

[0020] Preferably, the uplink and downlink signal processing circuits include an adaptive dynamic enhancement algorithm and a closed-loop feedback mechanism. The adaptive dynamic enhancement algorithm dynamically adjusts the amplification processing parameters according to the signal characteristic information received in real time. When the signal quality changes, such as the signal strength decreases or the noise increases, the algorithm automatically adjusts the gain and filtering parameters to maintain the stability of the signal quality. At the same time, the closed-loop feedback mechanism monitors the actual effect of the transmitted signal after the signal is transmitted, and feeds this information back to the signal processing circuit. By comparing the characteristics of the amplified signal with the original signal, the closed-loop feedback mechanism can identify any deviations and automatically adjust the working state of the amplification circuit, such as adjusting the amplification factor or filtering parameters to correct the deviation.

[0021] Preferably, in order to ensure the best transmission conditions for the signal, the system also includes a signal quality evaluation unit, which is located between the signal feature analysis module and the uplink and downlink signal processing circuits, and evaluates the received signal quality in real time; by analyzing the signal-to-noise ratio (SNR), bit error rate (BER) and throughput of the signal, the signal quality evaluation unit determines whether the signal reaches the best transmission conditions; when the signal quality is lower than a preset threshold, the evaluation unit will send a warning signal to the uplink and downlink signal processing circuits and start additional signal enhancement operations, which include increasing signal gain, adjusting frequency or selecting a new signal path to optimize signal quality, thereby ensuring signal stability and reliability.

[0022] Preferably, the signal transmitter is the last link in the system, responsible for transmitting the processed signal to the target area. The signal transmitter includes a receiving module that supports receiving signals in multiple frequency bands. Each module transmits signals for different frequency bands and performs appropriate filtering on the signals before transmission. The filtering operation ensures that only valid signals are transmitted, avoiding the propagation of unnecessary frequency bands and interference signals. The multi-band support capability of the system design enables the signal transmitter to cover a wide range of frequency bands from 700MHz to 5000MHz, supporting the processing and transmission of 4G LTE, 5G NR and future 6G standard signals.

[0023] Preferably, the system supports the reception and transmission of full-band multi-standard signals from 700MHz to 5000MHz, including 4GLTE and 5G NR, and has the ability to expand to other frequency bands and standards; through the multi-dimensional signal feature adaptive dynamic enhancement mechanism, the system can efficiently process signals in different frequency bands, ensure that signals of different standards do not interfere with each other, and can adjust the processing methods of signals of different standards as needed.

[0024] Preferably, during the signal reception and processing, the system optimizes the signal quality through the coordinated work of signal screening and enhancement mechanisms. First, the signal receiver screens the signal according to the frequency band module to ensure the input of effective signals. Then, the signal feature analysis module extracts multi-dimensional features of the signal and analyzes the signal feature information of the signal in real time. Finally, through the dynamic enhancement algorithm of the uplink and downlink signal processing circuits, the signal can be accurately amplified and transmitted to the target area.

[0025] (III) Beneficial effects

[0026] The present invention provides a new multi-frequency and multi-mode coverage system, which has the following beneficial effects:

[0027] 1. This system uses an integrated signal feature analysis module and an adaptive dynamic enhancement algorithm. It does not blindly amplify the signal of the entire bandwidth, nor does it require any prior information.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. 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.

[0030] The present invention describes in detail the specific implementation and operation process of a new multi-frequency and multi-mode coverage system. The system mainly includes a signal receiver, a signal feature analysis module, an uplink and downlink signal processing circuit and a signal transmitter, and these modules are connected in sequence to form a signal transceiver link. The goal of the system is to be able to efficiently receive, process and transmit a variety of communication standard signals in the 700MHz to 5000MHz frequency band. In this process, through the multi-dimensional signal feature adaptive dynamic enhancement mechanism, accurate signal processing in a complex signal environment is achieved.

[0031] First of all, as the core component of the system, the signal receiver is responsible for receiving RF signals in the frequency band of 700MHz to 5000MHz and ensuring the purity of the signal. In order to achieve this goal, the signal receiver is designed to be composed of receiving modules that support multi-band signal reception. Each module is responsible for receiving signals in different frequency bands and covers the entire frequency band. During the signal reception process, all received RF signals first pass through the filter. The main task of the filter is to remove interference from different frequency bands and stray signals to ensure that only valid signals are retained. The filtered signal enters the multi-dimensional signal feature adaptive dynamic enhancement mechanism. The system uses this mechanism to extract multi-dimensional features of the signal, mainly including the amplitude, phase and frequency of the signal, so as to identify different types of signals. Through this process, the system can accurately classify and screen the signals to ensure that only valid and pure signals continue to be processed, thereby maximizing the signal quality.

[0032] The subsequent signal processing process is the responsibility of the signal feature analysis module. After receiving the RF signal from the signal receiver, the module first couples the signal through a coupler and extracts key signal feature information such as communication standard, frequency band, frequency point, bandwidth, number of carriers and received signal strength indication (RSSI) based on the envelope detection method of signal energy. All extracted signal feature information will be transmitted to the uplink and downlink signal processing circuits in real time for subsequent signal amplification and processing.

[0033] After the signal characteristic information is transmitted to the uplink and downlink signal processing circuits, it first enters the signal detection unit. The signal detection unit determines whether the signal is valid based on the preset signal quality standard. For example, if the RSSI is greater than the set threshold, the signal is considered to be a valid signal. The valid signal is then targeted filtered through the filter to remove unnecessary frequency components in the signal. After filtering, the signal enters the gain adjuster and dynamically adjusts the amplification factor based on the extracted signal characteristic information to ensure the optimal signal amplification effect. Finally, the signal after filtering and gain adjustment enters the amplifier for amplification processing and is ready to be transmitted to the target area. The system can avoid blindly amplifying the signal of the entire frequency band and only amplify the valid signal, thereby avoiding unnecessary energy waste and improving the signal transmission efficiency.

[0034] The signal transmitter is the last link of the system, responsible for transmitting the processed signal to the target area. The signal transmitter includes a receiving module that supports receiving signals in multiple frequency bands. Each module is dedicated to transmitting signals in different frequency bands. Before transmitting, the signal transmitter will filter the signal appropriately to ensure that only valid signals are transmitted, avoiding the propagation of unnecessary frequency band signals or interference signals. The multi-band support capability of the system design enables the signal transmitter to cover a wide range of frequency bands from 700MHz to 5000MHz, supporting signal processing and transmission of 4G LTE, 5G NR, and future expansion to 6G and other standards.

[0035] The entire system is also equipped with an adaptive dynamic enhancement algorithm and a closed-loop feedback mechanism to ensure that the signal quality always remains in the best state. The adaptive dynamic enhancement algorithm can dynamically adjust the amplification processing parameters based on the signal characteristic information received in real time. When the signal quality changes, such as the signal strength decreases or the noise increases, the algorithm will automatically adjust the gain and filtering parameters to maintain the stability of the signal quality. The closed-loop feedback mechanism monitors the amplified signal effect after the signal is transmitted. When it is found that the signal quality does not meet expectations, the closed-loop feedback mechanism will automatically adjust the working state of the amplifier, such as adjusting the gain multiple or the bandwidth of the filter to correct any signal deviation. In this way, the system can not only maintain high precision during the signal processing process, but also adapt to changes in different signal environments.

[0036] Embodiment 2:

[0037] The difference between this embodiment and the first embodiment is that the focus of this embodiment is to describe how the system can achieve efficient coordination of signals between multiple communication standards. Similar to the first embodiment, the system in this embodiment is composed of a signal receiver, a signal feature analysis module, an uplink and downlink signal processing circuit, and a signal transmitter. The uniqueness of the system is that it supports the coordination of multiple communication standards such as 4G LTE and 5G NR, and can efficiently process signals from different frequency bands.

[0038] The signal receiver is also one of the core components of this system. Its main function is to receive RF signals in the frequency band of 700MHz to 5000MHz. In order to adapt to signals of different standards and frequency bands, the receiver is composed of receiving modules that support the reception of multiple frequency bands. Each module is responsible for receiving signals in different frequency bands. After receiving the signal, the signal first enters the filter module for preliminary filtering to remove unnecessary signal components. Then the signal is processed through a multi-dimensional signal feature adaptive dynamic enhancement mechanism. This mechanism performs real-time analysis on the amplitude, phase, frequency and other characteristics of the signal, identifies the communication standard and type of the signal, and ensures that only valid signals continue to be processed, avoiding interference caused by invalid signals.

[0039] In the signal feature analysis module, a part of the received RF signal is extracted through a coupler, and based on the envelope detection method of signal energy, characteristic information including communication standard, frequency band, frequency point, bandwidth, number of carriers, RSS I, etc. is extracted. This information will be transmitted to the uplink and downlink signal processing circuits in real time for subsequent signal amplification and transmission.

[0040] After receiving the signal characteristic information, the uplink and downlink signal processing circuit first performs a signal validity detection. The valid signal passes through the filter to remove unnecessary frequency components, enters the gain regulator for dynamic gain adjustment, and finally amplifies the signal through the amplifier before preparing for transmission. During the processing, the system ensures the stability of the signal quality and avoids unnecessary energy waste, thereby maximizing the signal transmission efficiency.

[0041] The signal transmitter is responsible for transmitting the final processed signal to the target area. The transmitter supports full-band signal transmission from 700MHz to 5000MHz through a receiving module that supports multiple frequency band signal reception, and performs appropriate filtering before transmission to ensure that only valid signals are transmitted. The system design not only supports the transmission of 4G LTE and 5G NR signals, but also has the ability to expand to 6G and other future communication standards.

[0042] During the multi-standard signal processing process, the system ensures accurate signal processing through an adaptive dynamic enhancement algorithm and a closed-loop feedback mechanism. When the signal quality changes, the system adjusts the signal processing parameters through real-time detection and optimizes the signal transmission effect through a closed-loop feedback mechanism, ensuring that the signals under each communication standard can be transmitted efficiently and stably.

[0043] Through this process, the present embodiment can efficiently process 4G LTE, 5G NR and other standard signals in a multi-frequency and multi-mode environment, realize the coordinated operation of signals, and ensure the quality and stability of signals.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
