[0037] The embodiments of the present application provide a self-organizing network waveform processing method of a space-air joint interference system and related equipment thereof, which is used for providing high-speed and reliable information transmission for the entire self-organizing network, and adopting a differentiated transmission mode for the transmission of command frames and data frames, so as to ensure that the data transmission has the requirements of flexibility and reliability.

[0038] In order for those skilled in the art to better understand the present application, the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0039] The terms "first", "second", "third", "fourth" and the like (if any) in the description, claims and drawings of the present application are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" or "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0040] The air-ground joint jamming environment construction generally includes a plurality of air interference loads and a plurality of ground interference devices, and a plurality of interference resources need to be self-organized network, uniformly distributed and used according to application requirements and planning, and controlled to implement jamming on a target. In the application, the air-ground joint networking adopts a wireless self-organized network mode for interconnection. The wireless self-organized network does not depend on existing fixed communication network infrastructure, and has flexible topology, strong invulnerability, and can well meet the requirements of special fields such as rapid deployment, flexible networking, strong invulnerability, good mobility, and no time and space restrictions. The application provides a self-organized network waveform processing method of an air-ground joint jamming system and related equipment, realizes high-speed and reliable information transmission for the entire self-organized network, and adopts a differentiated transmission mode for transmission of command frames and data frames, so as to ensure that the data transmission has the requirements of flexibility and reliability. The following will be described in detail.

[0041] Referring to Figure 1 One embodiment of the self-organized network waveform processing method of the air-ground joint jamming system in the embodiment of the application includes:

[0042] Step 101, when sending a signal, the FPGA sending end of one or more interference resources receives first data sent by the application end of the interference resource through an MII interface, wherein the interference resource includes an air interference load and a ground interference device, and the first data includes a command frame and a data frame; the first data is subjected to a first waveform data processing operation to be converted into a baseband signal suitable for radio frequency output.

[0043] Step 102, when receiving a signal, the FPGA receiving end of one or more interference resources receives a radio frequency signal through a power divider, and subjects the radio frequency signal to a second waveform data processing operation to parse the radio frequency signal into a data signal, and uploads the data signal to the application end of the interference resource through an MII interface.

[0044] For the construction of the air-ground joint jamming environment, the interference system generally composed of the ground and the air generally includes a plurality of air interference loads and a plurality of ground interference devices. In order to realize networking of a plurality of interference resources, and to be able to uniformly distribute and use according to application requirements and planning, and to implement jamming on other targets in the network in a controlled state. Therefore, in order to improve the jamming cooperation ability of the air-ground joint system, the self-organized network waveform processing scheme of the application aims to provide high-speed and reliable information transmission for the entire self-organized network, and ensure that the data transmission has the requirements of flexibility, stability and reliability.

[0045] In order to realize effective self-organizing network, the FPGA (Field Programmable Gate Array) arranged in the air interference load and the ground interference device is used to process the transceiving communication signal in the self-organizing network, and the processed transceiving communication signal has the characteristics of safety, stability, reliability and high efficiency, and is suitable for sending interference to the target in the interference system environment.

[0046] The interference resource includes the air interference load and the ground interference device, and the signal data needing to be processed in the self-organizing network generally includes the command frame and the data frame. When a certain interference resource in the self-organizing network system needs to send a signal, the FPGA sending end of the interference resource receives the command frame and / or the data frame sent by the application end of the interference resource through the MII interface, and these data need to be processed specially before being transmitted externally. The command frame and the data frame in the first data are processed and transformed into the baseband signal suitable for radio frequency output through the first waveform data processing operation, and then are sent out.

[0047] Further, when a certain interference resource in the self-organizing network system receives the signal sent by the other interference resource cooperating with it in the network, the FPGA receiving end of the interference resource receives the radio frequency signal through the power divider and analyzes the radio frequency signal into the data signal through the second waveform data processing operation, so as to upload the data signal to the application end of the interference resource through the MII interface of the interference resource, thereby realizing the cooperation between the air and ground interference resources.

[0048] Specifically, the transmission mode of the communication waveform of the present application adopts the TDD (Time Division Duplexing) mode, and the receiving and transmitting states are controlled by the transceiving switch of the radio frequency module. The first waveform data processing operation for the sending signal generally includes the processing of scrambling, coding, pilot adding and the like, and the data is transformed into the baseband signal suitable for radio frequency output; the processing of the receiving signal is the reverse operation of the sending part, and the second waveform data processing operation for the receiving signal generally includes the processing of AGC, channel estimation, decoding and the like, and the radio frequency signal is analyzed into the data signal, and then the data is uploaded to the application end through the Ethernet MII interface. Through the design of the bandwidth and the modulation mode, the rate greater than 6 Mbps can be realized in the whole network, and the transmission of 1 route 4 Mbps high-definition video and the information such as formation sharing data is provided for the whole network. The communication waveform in the embodiment of the present application adopts the transmission mode of the TDD mode, and all the algorithm modules in the framework of the whole communication waveform processing can be programmed, so that the core algorithm is self-controllable, and the reliability and stability can also be well guaranteed.

[0049] Further, the application also considers the problems of receiving sensitivity and the like in the second waveform data processing operation, and can improve the signal receiving gain by 2db-3db through soft decoding of the encoding by the soft decoding module. In the first waveform data processing operation, the peak-to-average ratio module is also considered to be used, and for the multi-carrier of the transmission signal relative to the single carrier, the problem of peak-to-average ratio is considered. For example, the peak-to-average ratio of IEEE802.11a system is about 9dbc (0.1%), so the sub-carrier is more than that of IEEE802.11a system, and therefore the peak-to-average ratio is controlled to be about 7dbc (0.1%) by adding the peak-to-average ratio module. In the second waveform data processing operation, the channel estimation and equalization module is also included, because the frequency selective fading and time selective fading occur in the communication process, the time dispersion effect in the process is handled by using the frame front end plus cyclic prefix processing mode, and the maximum support is 32us of multipath time delay, and the frequency dispersion effect is handled by using the anti-frequency offset mode to support the maximum frequency offset of 671.67Hz.

[0050] The encoding mode of the application in the signal processing adopts different encoding modes according to different transmission services, wherein the command frame adopts convolutional encoding, and the data frame adopts Turbo encoding. In the embodiment of the self-organizing network waveform processing method of the air-ground joint interference system, the first waveform data processing operation includes:

[0051] The command frame of the first data is channel encoded by using the 1 / 2 punctured code corresponding to the standard convolutional code, and is transmitted by using the BPSK mapping modulation mode. The data frame of the first data is encoded by using the Turbo code, and is transmitted by using the adjustable constellation mapping mode. The combination of the convolutional code and the BPSK mapping for the command frame and the combination of the Turbo code and the adjustable constellation mapping for the data frame make the transmission data of the sent signal become the most reliable transmission mode.

[0052] The combination of the Turbo code and the adjustable constellation mapping for the data frame can realize the transmission of different data rates. The Turbo code is the encoding mode applied to the LTE system, and the decoding limit is very close to the Shannon limit. In addition, the different puncturing and adjustable constellation mapping after encoding make the self-organizing network system of the application realize the rate bandwidth of 6Mbps-24Mbps.

[0053] Further, in another embodiment of the self-organizing network waveform processing method of the air-ground joint interference system, the first waveform data processing operation further includes:

[0054] The data obtained by encoding the command frame and the data obtained by encoding the data frame are punctured according to the preset period.

[0055] In the implementation, the puncturing operation is performed on the coded data, that is, some relatively unimportant data bits are periodically deleted, and the convolutional coding with the puncturing operation is introduced, which is also called punctured convolutional code. Of course, after the puncturing operation is performed during the coding, the depuncture operation is performed during the decoding, that is, the punctured bit positions are filled before the decoding. For example, in the case that some coded bits are deleted at the code rate of 1 / 2, the puncturing operation is performed on the coded data at the code rate of 3 / 4, that is, six coded bits are input, two of which are deleted, and the remaining four bits are output at the clock of 4 / 3, and finally the code rate is 3 / 4 divided by 2 / 3, that is, 1 / 2. By periodically deleting some relatively unimportant data, the data redundancy is reduced, and the transmission efficiency of the transmission service data is improved as a whole.

[0056] Further, in another embodiment of the self-organizing network waveform processing method of the air-ground joint interference system, during the channel coding process of the command frame of the first data by using the 1 / 2 punctured code corresponding to the standard convolutional code, the interleaving module is used to perform the grouped interleaving processing on the command frame.

[0057] In the implementation, considering the burst error resistance, the command frame needs to be interleaved by using the corresponding interleaving module during the coding process, which is different from the interleaving of the Turbo code coding of the data frame. In the present application, the grouped interleaving mode is used. For example, a 4*5 grouped interleaver is used to describe the implementation of the grouped interleaver. The bit data is written on the row of the matrix, and the bit data is read on the column of the matrix, or vice versa. During the decoding of the second waveform data processing operation, the deinterleaving and interleaving are opposite, that is, the bit is restored to the original order. The corresponding deinterleaver is a 5*4 matrix. The received bit is written in different rows, and then read out according to different columns. In the implementation process, the grouped interleaver can be realized by using the RAM in the FPGA.

[0058] Further, in another embodiment of the self-organizing network waveform processing method of the air-ground joint interference system, the method further comprises:

[0059] According to different modulation modes, the complex numbers after the mapping of the command frame and the data frame are respectively multiplied by the corresponding preset normalization factor, so as to obtain all the output data with the same average power after the mapping.

[0060] Specifically, during transmission, the modulation mode of the service frame can change, for example, the command frame adopts the most reliable BPSK modulation, and the data frame can adopt another modulation. Generally, the data frame has four different modulation modes, i.e., BPSK, QPSK, 16QAM or 64QAM modulation, according to different rate requirements. In order to make all the mappings have the same average power, the mapping needs to be normalized. The complex number after mapping is multiplied by a normalized quantity to obtain the output data.

[0061] Further, in another embodiment of the self-organizing network waveform processing method of the air-ground joint interference system, before the encoding processing of the command frame of the first data, the method further comprises:

[0062] The command frame sequence is scrambled by using a scrambler polynomial to perform a scrambling operation on the command frame.

[0063] In a specific implementation, in order to avoid a long string of 0 or 1, a scrambler is considered to be added in the digital waveform communication system of the present application, and the statistical characteristics of the digital signal are changed without increasing redundant data. Correspondingly, at the receiving end, the digital information needs to be recovered by descrambling. For example, in the processing of the command frame, a scrambling operation needs to be performed first. The present application designs a polynomial generator: S(x) = x 7 +x 4 +1. The scrambler is essentially a feedback shift register, and its output is an m-sequence. The m-sequence can most effectively scramble the input sequence to minimize the correlation between the output digital symbols.

[0064] When the command frame is transmitted, the initial state of the scrambler should be set to a non-zero pseudo-random state. For example, when the initial state is all 1, the 127-bit sequence repeatedly generated by the scrambler is 00001110 1111001011001001 0000001000100110 00101110 10110110 00001100 11010100 1110011110110100 0010101011111010 01010001 10111000 11111111.

[0065] The descrambler has the same polynomial generator structure as the scrambler. Assuming that the original digital information is Din k , after scrambling, it becomes:

[0066]

[0067] where Scram k is the output data after scrambling; S k is the feedback data of the scrambler.

[0068] For the descrambling module,

[0069]

[0070] Wherein, Descram k S' is the output data after descrambling, k is the feedback data of the descrambler.

[0071] Obviously, in order to successfully realize descrambling, the feedback data of the descrambler and the scrambler must be equal at each corresponding time, that is, the 7 state values of the sequence generator at each time in the process of scrambling and descrambling must be equal.

[0072] Further, in another embodiment of the self-organizing network waveform processing method of the air-ground joint jamming system, the baseband framing of the first data is designed as follows: the command frame is set with 16 bits b15-b0, the data frame is set with up to 3960 bits, and the tail section for CRC32 checking of the data frame is set with 32 bits.

[0073] In specific implementation, the service frame data, i.e., the baseband framing of the first data, is designed as follows: the command frame is set with 16 bits b15-b0 to determine how the following data section is transmitted in terms of coding and modulation mode; the data frame is set with up to 3960 bits, and the tail section for CRC32 checking of the data frame is set with 32 bits.

[0074] As can be seen, in the embodiment of the present application, in order to realize the wireless ad hoc network interconnection and low-delay information interaction, a communication waveform solution applied to the ad hoc network is provided in the system environment of the air-ground joint interference, the first data transmitted by the application end of the interference resource is received by the sending end of one or more interference resources, and the first waveform data processing operation is performed on the first data to transform the first data into a baseband signal suitable for radio frequency output; and the radio frequency signal is received by the receiving end of one or more interference resources, and the second waveform data processing operation is performed to parse the radio frequency signal into a data signal, and the data signal is uploaded to the application end of the interference resource. Specifically, the sending part of the interference resource receives the data transmitted by the application end, and then the data is transformed into a baseband signal suitable for radio frequency output through scrambling, encoding, pilot addition and the like, the information bit sequence of the baseband signal is modulated into a PSK / QAM symbol, inverse fast Fourier transform is performed on the corresponding symbol to transform the symbol into a time domain signal, and the time domain signal is transmitted through the corresponding wireless channel; and the receiving part of the interference resource is reversely operated with the sending part, the radio frequency signal is parsed into a data signal through AGC, channel estimation, decoding and the like, and the data is uploaded to the application end. Through the design of the bandwidth and the modulation mode, a rate greater than 6Mbps can be realized to provide the transmission of the data information for the entire network. The present application provides high-speed and reliable information transmission for the entire ad hoc network, and a differentiated transmission mode is adopted for the transmission of the command frame and the data frame, so that the data transmission has the requirements of flexibility and reliability.
