而且效果明显。

Abstract

In time-phase modulation systems

the aliasing signals of multi-channel time-phase modulation signals received at the multiple sensor ports are separated into relatively independent segments by adopting the fast Independent Component Analysis（ICA）algorithm so that their phase abrupt features can be extracted and their detection and demodulation accomplished.Simulation results indicate that this technique can extract the phase abrupt features of time-phase modulation signals with distinct effects.
