摘要
针对双梯度的盲源分离算法进行了研究,以信号的峭度为代价函数对其进行了改进.仿真试验分别对通信信号和雷达信号实现了分离,改进算法在收敛速度和稳态误差方面具有显著的优势.同时指出将盲分离方法用于雷达信号的分离,具有广阔的应用前景.
A bigradient blind source separation method was studied. An improvement was made with kurtosis of a signal as contrast function. Simulation results were performed to demonstrate its effectiveness for seperation of communication signal and radar signal, respectively. The improved method has great advantages over original method in convergence speed and steady-state error. The blind source separation method has great potential application for the radar signal＇ s seperation.
