Description

Technical Field

[0001] This application relates to the field of signal processing technology, and in particular to a method and system for rapid generation of arbitrary combinations of multi-mode and multi-channel signals. Background Technology

[0002] The widespread use of various electronic devices, such as radar, communication equipment, and electronic countermeasures equipment, generates dense and redundant electromagnetic signals. To enable reconnaissance and jamming equipment to operate effectively in complex electromagnetic environments, it is necessary to simulate realistic electromagnetic backgrounds and generate universal communication signals. This requires flexible signal patterns and controllable parameters, capable of generating various required frequency bands, signal patterns, dynamically controllable electromagnetic environment background signals, and standard detectable and demodulated communication signals based on different backgrounds and experimental conditions. However, current multi-channel signal generation methods and equipment suffer from drawbacks such as high cost, poor flexibility, small bandwidth, and limited waveform formats, failing to meet the needs of more scenarios. Furthermore, most electromagnetic environment construction equipment is independent of jamming and radar equipment, leading to a single system mode, low hardware resource utilization, and limited application scenarios. Summary of the Invention

[0003] In view of this, this application provides a method and system for rapid generation of multi-mode, multi-channel signals by arbitrary combination.

[0004] This application discloses a rapid generation method for arbitrarily combined multi-mode and multi-channel signals, used in simulated complex electromagnetic environments, comprising: The display control module performs unified configuration of all parameters. After configuration, it encapsulates all parameters into a parameter configuration frame according to the preset parameter configuration frame protocol and sends it to the configuration frame management module. All parameters include the system's operating mode, the number of signals transmitted, and the waveform types and waveform parameters of each signal. The operating modes include environmental configuration mode, interference mode, and radar mode. The waveform parameters include modulation scheme, symbol rate, and frequency. The configuration frame management module parses the parameter configuration frame from the display control module according to the predefined frame protocol, extracts the frequency point of each signal from the parsed data, obtains the center frequency of the RF chip and the frequency deviation of each signal relative to the center frequency based on the frequency point of each signal, reconstructs a new parameter configuration frame with the center frequency and frequency deviation and sends it to the multi-signal generation module. The multi-channel signal generation module processes the parameter configuration frames sent by the configuration frame management module to generate radio frequency signals. The signal processing includes parameter parsing and loading, signal scrambling, interleaving, modulation, rate conversion, up-conversion, and multi-channel signal combining.

[0005] Furthermore, after receiving the parameter configuration frame from the display control module, the configuration frame management module verifies the frame header identifier according to the frame protocol to determine whether the parameter configuration frame meets the requirements. If it meets the requirements, it enters the frequency point calculation process. After completing the frequency point calculation process, the configuration frame management module reorganizes the center frequency and each channel frequency offset into a new parameter configuration frame and sends it to the multi-channel signal generation module through the LVDS interface. If it does not meet the requirements, the parameter configuration frame is directly discarded.

[0006] Furthermore, the frequency point calculation process includes: The configuration frame management module extracts the frequency point information of all valid paths within the parameter configuration frame. It then searches for the maximum and minimum values ​​in the frequency point information and obtains the corresponding average value based on these values. This average value is then used as the center frequency required by the RF chip. The frequency difference between the configured frequency point of each effective path and the center frequency is calculated sequentially to obtain the frequency deviation of each signal relative to the center frequency.

[0007] Furthermore, the multi-channel signal generation module parses the current working mode, the number of signals transmitted, and the physical layer parameters of each signal according to the parameter configuration frame issued by the configuration frame management module; the parsed parameters are imported into the corresponding signal processing paths for updating; after all signal parameters are configured, the physical layer processing module is started to execute the physical layer processing flow.

[0008] Furthermore, the multi-channel signal generation module consists of a parameter parsing module, a data input module, a physical layer processing module, and a radio frequency transmission channel; The parameter parsing module parses the current working mode, the number of signals transmitted, and the physical layer parameters of each signal according to the parameter configuration frame issued by the configuration frame management module, and sends them to the physical layer processing module so that the physical layer processing module can perform relevant configurations, including scrambling configuration, coding parameter configuration, spread spectrum configuration, interleaving table, modulation mode configuration, rate matching parameter configuration, and DUC parameter configuration. The data input module receives source data and sends it to the physical layer processing module; The physical layer processing module obtains multiple digital signals based on the received signals and related configurations, combines them, and outputs them uniformly to the radio frequency transmission channel. The radio frequency transmission channel transmits the received combined signal.

[0009] Furthermore, the physical layer processing module includes multiple branches; Each branch receives data sent by the data input module, generates waveform data corresponding to the data according to the corresponding working mode, and outputs the obtained waveform data to the radio frequency transmission channel.

[0010] Furthermore, each branch group includes multiple data transmission branches and signal processing branches; If the working mode is the existing waveform mode, the data received by the data input module will be input into the existing waveform module in the data transmission branch and directly output to the signal combining module. If the working mode is radar mode, the data received by the data input module is input into the pulse generation module in the data transmission branch and directly output to the DUC frequency converter module. If the working mode is not radar mode, that is, the working mode is environmental configuration mode or jamming mode, then it is determined whether the modulation system of the parameter configuration is digital modulation. If it is digital modulation, the data received by the data input module is input into the signal processing branch, and after scrambling, encoding, spreading, interleaving, modulation and rate conversion, it is output to the DUC frequency converter module. If the operating mode is not radar mode and the modulation scheme is analog modulation, the data received by the data input module will be input into the DDS analog signal generation module in the data transmission branch and output to the DUC frequency converter module. The DUC frequency converter module performs down-conversion processing on the received data to obtain a frequency conversion signal and sends it to the signal combining module. The signal combining module combines the received signals and outputs one signal to the radio frequency transmission channel.

[0011] Furthermore, the existing waveform module, pulse generation module, and DDS analog signal generation module belong to different data transmission branches.

[0012] This application also discloses a rapid generation system for arbitrary combinations of multi-mode and multi-channel signals, used to implement the aforementioned rapid generation method for arbitrary combinations of multi-mode and multi-channel signals, comprising: The display control module is used to uniformly configure the system's operating mode, the number of signals transmitted, and the waveform types and parameters of each signal. After configuration, it encapsulates all parameters into a parameter configuration frame according to the preset parameter configuration frame protocol and sends it to the configuration frame management module. The operating modes include environment configuration mode, jamming mode, and radar mode. The parameters include modulation scheme, symbol rate, and frequency. The configuration frame management module is used to parse the parameter configuration frame from the display control module according to the predefined frame protocol, extract the frequency point of each signal from the parsed data, obtain the center frequency of the RF chip and the frequency deviation of each signal relative to the center frequency based on the frequency point of each signal, reconstruct a new parameter configuration frame with the center frequency and frequency deviation and send it to the multi-signal generation module. The multi-channel signal generation module is used to process the parameter configuration frames sent by the configuration frame management module to generate radio frequency signals. The signal processing includes parameter parsing and loading, signal scrambling, interleaving, modulation, rate conversion, up-conversion, and multi-channel signal combining.

[0013] Due to the adoption of the above technical solution, this application has the following advantages: The system supports three modes: environment setup, jamming, and radar. Its design goal is to efficiently simulate complex electromagnetic environments and adapt to various application scenarios.

This multiplexing technology ensures extremely high concurrency performance while effectively reducing the complexity of system design and hardware resource overhead, enabling the system to simulate dense and complex electromagnetic signal environments with higher efficiency and reliability, meeting the growing testing and evaluation needs.

[0025] This application also provides an embodiment of a rapid generation system for arbitrary combination of multi-mode and multi-channel signals, used to implement the rapid generation method for arbitrary combination of multi-mode and multi-channel signals described in the above embodiment, comprising: The display control module is used to uniformly configure the system's operating mode, the number of signals transmitted, and the waveform types and parameters of each signal. After configuration, it encapsulates all parameters into a parameter configuration frame according to the preset parameter configuration frame protocol and sends it to the configuration frame management module.

The multi-channel signal generation module is used to process the parameter configuration frames sent by the configuration frame management module to generate radio frequency signals. The signal processing includes parameter parsing and loading, signal scrambling, interleaving, modulation, rate conversion, up-conversion, and multi-channel signal combining.

[0026] For ease of understanding, this application provides a more specific embodiment: This application, based on ZYNQ, RF transceiver chips, and a PC, proposes a method and system for rapid generation of multi-mode, multi-channel signals through arbitrary combinations. Figure 1As shown. The software architecture of this application mainly consists of three modules: display control, configuration frame management, and multi-channel signal generation. These modules work together to complete the entire process from task configuration to RF signal generation. The display control module, as the core of system control, is responsible for setting three operating modes: environment setup, jamming, and radar. It also allows users to flexibly configure the number of signals transmitted and the waveform types of each signal in each mode. The waveform library supports custom waveforms and existing waveforms from the Red and Blue teams. For custom waveforms, detailed parameters such as modulation scheme, frequency, and rate can be configured independently. All configuration information is ultimately framed and sent to the configuration frame management module. The configuration frame management module is responsible for the central processing and forwarding of signal configuration information. Based on a predefined frame protocol, it parses the configuration data from the display control module, extracts the frequency of each signal, and then calculates the center frequency of the RF chip and the frequency offset of each signal relative to this center frequency. After the calculation is completed, this module reorganizes the center frequency and frequency offset and other key parameters into a new data frame and sends it to the multi-channel signal generation module through a high-speed LVDS interface. The multi-channel signal generation module is the final execution unit for physical layer waveform generation. Its core functions include parameter parsing and loading, signal scrambling, interleaving, modulation, rate conversion, up-conversion, and multi-channel signal combining, forming a complete physical layer processing flow.

[0027] This system supports three modes: environment setup, jamming, and radar. Its design goal is to efficiently simulate complex electromagnetic environments and adapt to various application scenarios. Its core performance is characterized by high concurrency, high flexibility, and wide bandwidth coverage. Through advanced physical layer module multiplexing technology, the system can simultaneously generate up to 60 waveforms of different modes in a single transmission. The mode, rate, and frequency of each signal can be independently configured, and the instantaneous transmission signal bandwidth can reach 1 GHz. This multiplexing technology ensures extremely high concurrency performance while effectively reducing system design complexity and hardware resource overhead, enabling the system to simulate dense and complex electromagnetic signal environments with higher efficiency and reliability, meeting the growing needs of testing and evaluation.

[0028] This application uses a display control module to uniformly configure the system's operating mode, the number of signals transmitted, and the waveform types and parameters (such as modulation scheme, symbol rate, frequency, etc.) of each signal. After configuration, all parameters are encapsulated into data frames according to a preset parameter configuration frame protocol and sent to the configuration frame management module for further processing.

[0029] After receiving the parameter configuration frame from the display control module, the configuration frame management module first verifies the frame header identifier according to the frame protocol to determine if it is a valid parameter configuration frame. If the verification passes, the subsequent frequency point calculation process begins; if the verification fails, the data frame is discarded. During the frequency point calculation phase, the module extracts the frequency point information of all valid paths within the frame, searches for the maximum and minimum values, and calculates their average value to obtain the local oscillator frequency required by the RF chip. Subsequently, it calculates the difference between the configuration frequency point of each valid path and the local oscillator frequency, thus obtaining the frequency offset adjustment value required for each signal in the multi-channel signal generation module. After all calculations are completed, the configuration frame management module reorganizes the local oscillator frequency and other parameters such as the frequency offset of each path into a new parameter configuration frame and sends it to the multi-channel signal generation module for subsequent signal generation and frequency conversion processing.

[0030] The multi-channel signal generation module of this application is implemented through flexible parameter configuration and combining, as follows: Based on the parameter configuration frame issued by the configuration frame management system, the current operating mode, the number of signals transmitted, and the physical layer parameters of each signal are parsed out. The parsed parameters are then imported into the corresponding signal processing paths for updates. After all signal parameters are configured, the physical layer processing flow, including modulation and frequency conversion, is initiated. To achieve multi-mode waveform generation while balancing system complexity and resource efficiency, the physical layer adopts a modular reuse architecture, such as... Figure 2 As shown, it mainly consists of a physical layer processing module, a parameter parsing module, a data input module, and an RF transmission module. The physical layer processing module has the capability to process 60 parallel signals, each supporting five processing modes: environmental configuration, interference, radar, and various existing waveforms. The scrambling, encoding, spreading, interleaving, framing, modulation, rate matching, DDS analog signal generation, polyphase filtering, pulse generation, and DUC frequency conversion functions for each signal all reuse the same set of hardware modules. Each functional module adopts a parameterized design; the parameter parsing module distributes the parsed configuration information to the parameter configuration interface of the corresponding valid path, achieving flexible function adaptation. Finally, all path signals are digitally combined and output to the RF transmission channel, completing the concurrent generation and transmission of multiple signals.

[0031] The specific implementation process of the multi-channel signal generation module is as follows: Figure 3 As shown, the details are as follows: 1) Parse the parameter fields related to the mode and effective path within the parameter frame; 2) Update the parameters of the physical layer processing module to enable the data input interface of the effective path; 3) If the waveform pattern is already in use, the input is taken from the existing pulse module and directly output to the signal combining module; 4) In radar mode, the pulse is input from the pulse generation module and output directly to the signal combining module; 5) If it is not radar mode, then determine whether it is digital modulation; 6) If it is digital modulation, the signal is input from the source, and after encoding, spreading, interleaving, modulation, and rate conversion, it is output to the DUC frequency converter module; 7) If it is analog modulation, the signal is input from the DDS analog signal generation module and then output to the DUC frequency converter module; 8) The DUC module obtains a valid signal interface, performs frequency conversion, and outputs it to the signal combining module, which combines different signals and outputs them to the RF transmission channel.

[0032] This application supports real-time switching between three modes: environmental configuration, jamming, and radar. In the simulated electromagnetic environment configuration mode, it can simultaneously transmit 60 channels of waveforms in 10 different modes, with signal patterns including AM, FM, CW, 2FSK, 4FSK, 8FSK, BPSK, QPSK, and 8PSK. This application allows for individual setting of scrambling, encoding, spreading, modulation scheme, symbol rate, and frequency parameters for each signal, with the symbol rate not exceeding half the sampling rate of the RF transceiver chip and the frequency not exceeding the RF chip's transmission range. This application can occupy a wide frequency band for transmitted signals: 1.5MHz to 6GHz, and in jamming mode, it can transmit jamming signals occupying 1GHz of bandwidth at a time. The physical layer of this application employs module multiplexing technology, ensuring concurrent transmission of 60 signals while reducing design complexity and hardware resource consumption. The physical layer uses only one ZYNQ chip, with overall resource consumption accounting for 70%.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them. Although this application has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this application. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this application should be covered within the protection scope of the claims of this application.
