摘　　要：为扩展通信网络的频谱宽度,从而充分提高通信信号的跳频传输能力,提出基于稀疏重构的网络通信跳频信号参数估计算法。根据稀疏测度矩阵,计算正则化重构指标的具体数值,通过统计信号协方差的处理方式,完成基于稀疏重构的通信信号调制。在此基础上,定义估算核函数,联合已知的跳频参量提取结果,确定网络通信环境中的瞬时信号传输权限,实现对网络通信跳频信号参数的估量与计算,完成基于稀疏重构的网络通信跳频信号参数估计算法的设计。实验结果表明,与深度学习型估算方法相比,在稀疏重构原则的作用下,通信网络的频谱宽度得以扩展,符合提高通信信号的跳频传输能力的实际应用需求。In order to expand the spectrum width of communication network and fully improve the frequency hopping transmission ability of communication signal,a parameter estimation algorithm of network communication frequency hopping signal based on sparse reconstruction is proposed. According to the sparse measure matrix,calculate the specific value of the regularization reconstruction index,and then complete the communication signal modulation based on sparse reconstruction through the processing method of statistical signal covariance. On this basis,the estimation kernel function is defined,combined with the known frequency hopping parameter extraction results,the instantaneous signal transmission authority in the network communication environment is determined,the estimation and calculation of network communication frequency hopping signal parameters are realized,and the design of network communication frequency hopping signal parameter estimation algorithm based on sparse reconstruction is completed. The experimental results show that compared with the deep learning estimation method,under the sparse reconstruction principle,the spectrum width of the communication network can be expanded,which meets the practical application requirements of improving the frequency hopping transmission ability of the communication signal.
