Solutions to Data Reception with Improve Blind Source Separation in Satellite Communications

摘要

In satellite network, when the data is transmitted to the nearest base station on the ground with satellite cross-links, the attack appears to come from one satellite, but it's actually from multiple satellites. Especially in non-cooperative communication, the separation of received signals is a difficult task. In this article, solve the problem with blind source separation method is feasible. The contributions in this paper is as follows, firstly, signal sparsity is completed by computing the Short Time Fourier Transform (STFT), secondly, we separate the mixed source signals by improved PSO clustering. At last, we verify the proposed method by several simulations. The experimental results demonstrate the effectiveness of the proposed method.
