基于最大熵化法的卫星信号盲分离

Blind Separation of Satellite Signals Based on the Maximum Entropy

该文研究的问题是从经过卫星信道的混合信号中分离出相互独立的原始信号。解决这类问题的传统方法往往是采用盲解卷积的算法,但是这种方法的计算量很大,需要对各个径的参数进行调整。该文利用卫星信道的特点,提出了基于最大熵的盲分离算法,极大地减小了计算量。最后的仿真结果表明了算法有效性。

The problem that this paper discusses is how to separate the origin signals from the mixed satellite signals. The traditional method to solve the kind of problem adopts the algorithm of blind convolution which needs much account to adjust the all pathway parameters. However using the characteristic of satellite channel this paper put forwards the blind separation algorithm based on maximum entropy which can deduce the calculation too much.The results of simulations testify the validity.
