[0027] The following details the specific implementation of the above-mentioned integrated conduction waveform parameter optimization method.

[0028] Step 1: Construct a unified conduction waveform signal frame format by sharing a waveform between the navigation signal and the communication signal.

[0030] Step 2 involves establishing a multi-objective optimization model for the integrated conduction waveform parameters to obtain all available combinations of integrated conduction waveform parameters that meet the requirements of navigation measurement and communication performance, and then selecting the optimal combination of integrated conduction waveform parameters. Specifically, this includes: Step 2.1: Construct a navigation measurement performance and communication performance index system.

[0037] (4) Interference tolerance X , is represented as:

[0038] in, B w For frequency hopping operating bandwidth, B s The instantaneous bandwidth of the signal. SNR Minimum received signal-to-interference-plus-noise ratio, in dB. L i To account for losses, the unit is dB; For interference tolerance X The correlation function.

[0039] Step 2.2: Based on the navigation measurement performance index and communication performance index in the index system, establish a multi-objective optimization model for the integrated navigation waveform parameters, solve the model, and obtain all available integrated navigation waveform parameter combinations that meet the requirements of navigation measurement performance and communication performance.

[0040] First, to simultaneously consider the communication and measurement performance of the integrated conduction waveform, arrival time measurement accuracy thresholds are established sequentially. Communication rate threshold R b,th Communication distance threshold d th Interference tolerance threshold X th Antenna radiated power constraint EIRP th Then, based on the navigation measurement performance indicators and communication performance indicators in the indicator system, the integrated navigation waveform parameters are jointly modeled for multi-objective optimization. The established multi-objective optimization model for the integrated navigation waveform parameters is expressed as follows:

[0041] in, To ensure accuracy in arrival time measurement, R b For communication rate, d For communication distance, X To mitigate interference, For arrival time measurement accuracy threshold , R b,th For communication rate threshold, d th This is the communication distance threshold. X th This is the threshold value for interference tolerance. EIRP th Antenna radiated power constraint; To meet the required antenna radiated power Synchronization duration Symbol rate carrier frequency Modulation style The ratio of data duration to time slot length Encoding rate Frequency hopping operating bandwidth The integrated waveform parameter combination for conduction, wherein the time slot length is the sum of the synchronization duration, data duration, and protection duration; Symbol rate Range of values For encoding bitrate r Range of values Modulation style Mod gather, The ratio of data duration to time slot length. Range of values Antenna radiated power Range of values Frequency hopping operating bandwidth scope, To synchronize duration Range of values carrier frequency The range of values; argmax(.) is the value of the input variable for which the function reaches its maximum value; argmin(.) is the value of the input variable for which the function reaches its minimum value; For communication rate R b The correlation function; For communication distance d The correlation function; For interference tolerance X The correlation function; For accuracy of arrival time measurement The correlation function.

[0042] Step 2.3: Calculate the weighting results of all available integrated navigation waveform parameter combinations using navigation measurement performance and communication performance, and select the integrated navigation waveform parameter combination with the highest weighting result to achieve the goal of simultaneously considering navigation measurement performance and communication performance.

[0043] In this embodiment of the invention, the calculation of the weighting results of all available integrated conduction waveform parameter combinations using navigation measurement performance and communication performance specifically includes: Step 2.3.1: Based on all available combinations of integrated conduction waveform parameters, calculate the arrival time measurement accuracy of the navigation measurement performance index for each combination. and communication rate, a key performance indicator for communication. R b ( i ), communication distance d ( i Interference tolerance X ( i ).

[0044] Step 2.3.2: Measure the arrival time accuracy of navigation measurement performance indicators for each combination. and communication rate, a key performance indicator for communication. R b ( i ), communication distance d ( i Interference tolerance X ( i After normalization, the normalization factors for each performance index are obtained, expressed as follows:

[0045]

[0046]

[0047]

[0048] in, For the first i A normalization factor for the arrival time measurement accuracy of the integrated conduction waveform parameters. For the first i A communication rate normalization factor that can be used for the integrated conduction waveform parameters. For the first i A communication distance normalization factor that can be used for integrated conduction waveform parameters. For the first i An anti-interference tolerance normalization factor that can be used for the integrated conduction waveform parameters.

[0049] Step 2.3.3: Different normalization factors have the same optimization direction and similar value ranges. Based on the requirements of different application scenarios for communication performance indicators and navigation measurement performance indicators, different weight coefficients are assigned to different normalization factors and linearly weighted, transforming multi-parameter joint optimization into single-objective optimization. Therefore, we obtain:

[0050]

[0051] in, w 1 represents the weighting coefficient for the accuracy of time measurement. w 2 represents the communication rate weighting coefficient. w 3 represents the communication distance weighting coefficient. w 4 represents the interference tolerance weighting factor. F ( i ) is the first i The weighting result of the integrated conduction waveform parameters can be used.

[0052] Step 3: Combine the optimal integrated conduction waveform parameters to form the optimal integrated conduction waveform signal frame using the aforementioned integrated conduction waveform signal frame format. That is: Set the synchronization duration, symbol rate, modulation pattern, antenna radiated power, operating bandwidth range, and carrier frequency in the synchronization segment of the optimal combination of integrated conduction waveform parameters. Set the data duration, coding rate, symbol rate, modulation pattern, antenna radiated power, operating bandwidth range, and carrier frequency in the data segment from the optimal combination of integrated conduction waveform parameters; The protection duration is determined based on the data duration, synchronization duration, and the ratio of data duration to time slot length, and then set in the protection segment.

[0053] Depend on Figure 2 As can be seen, the integrated conduction waveform signal frame format constructed in this embodiment of the invention possesses communication data-assisted measurement capabilities. The receiving end can fully utilize the communication system's ability to receive unknown data symbols, transforming the unknown data symbols into known data symbols through demodulation and decoding. Unified measurement processing of synchronization symbols and data symbols is then performed, effectively extending the synchronization symbol processing time and improving measurement accuracy. Under a 20MHz signal bandwidth, the TOA (Time of Arrival) measurement accuracy of non-data-assisted and data-assisted methods was analyzed and compared. Non-data-assisted methods only use synchronization symbols for TOA measurement, while data-assisted methods combine data symbols and synchronization symbols to transform unknown data symbols into known data symbols, effectively extending the synchronization length and improving TOA measurement accuracy. For example, the synchronization segment symbol length is 600 bits, and the data symbol length is 3600 bits. Figure 3 This paper presents a comparison of measurement performance results for integrated conduction waveform communication, where the horizontal axis represents the ratio of symbol energy Es to noise power spectral density No, and the vertical axis represents the TOA deviation. Figure 3 It can be seen that, with a measurement accuracy of 1 ns, the data-assisted TOA measurement method has a performance advantage of about 7 dB compared with the non-data-assisted TOA measurement method.
