communication reconnaissance signal processing blind source separation independent component analysis
With the Kullback-Leibler divergence as cost function,the relative gradient is used to deduce a separation algorithm for communication signal blind separation in the communication reconnaissance.The algorithm given in the paper is proved stable in theory.Simulation results show that this algorithm can effectively separate the original signals from the observed signals with any carrier frequency and any modulation if only these original signals are independent each other.When original signals are not absolutely independent,their performance is decreased a little.
