Abstract

In this paper, we present a blind signal separation method for time-frequency overlap communication signals. The method is derived in the general context of independent component analysis, which we refer to as the signal minimum projection algorithm (SMP). Unlike conventional blind signal separation algorithms that use signal independence, we determine whether the signal is independent by observing the length of its projection on each axis of the scatter plot, and give a detailed proof. Simulation results show that this algorithm runs fast while maintaining good separation performance compared to other algorithms.
