认知型宽带恒模阵列水声通信多用户信号分离与干扰抑制算法
Source Separation and Jamming Suppression for Underwater Acoustic Communication Systems with Cognitive Capability
摘要
Abstract
A type of wide-band space-time constant modulus array algorithm for multi-user signal acquisi-tion and interference suppression in underwater acoustic communication system is proposed to realize multi-user signal extraction and wide-band interference suppression .Compared with the conventional constant modulus array ,it has stronger ability of multi-path and interference suppression .As an impor-tant part of cognitive underwater communication system ,the time-frequency analysis and the instantane-ous autocorrelation modulation algorithm for feature extraction provide an effective technique to classify the multi-user signals and interferences obtained by the wide-band constant modulus array ,providing a solution to demodulation for different users and interference suppression .The performance of the cogni-tive processing structure is proved via numerical simulations .关键词
