摘　　要：针对基于连续相位调制和线性调频(CPM-LFM)雷达通信一体化信号的通信解调问题,提出了一种针对该一体化信号的通信解调处理方案.通过脉冲检测、通信信号分离、低通滤波、频偏与相偏估计、频偏与相偏修正、码元检测六个步骤,实现离散基带接收一体化信号的通信信号处理功能.仿真结果表明,采用该方案在加性高斯白噪声下可以解调出通信码元,验证了CPM-LFM雷达通信一体化信号解调处理方案的正确性.Aiming at the communication of the radar-communication integrated shared signal based on continuous phase modulation and linear frequency modulation(CPM-LFM),this paper presents a communication demodulation processing scheme for the integrated signal.The communication signal processing function of discrete baseband receiving integrated signal is achieved through six steps including pulse detection,communication signal separation,low pass filter,estimation and correction of frequency offset and phase offset,and symbol detection.Simulation results show that the proposed scheme can demodulate the communication symbols under the additive white Gaussian noise,which verifies the correctness of CPM-LFM radar-communication integrated signal demodulation processing scheme.
