基于最大熵化法的衛(wèi)星信號盲分離
Blind Separation of Satellite Signals Based on the Maximum Entropy
-
摘要: 該文研究的問題是從經(jīng)過衛(wèi)星信道的混合信號中分離出相互獨立的原始信號。解決這類問題的傳統(tǒng)方法往往是采用盲解卷積的算法，但是這種方法的計算量很大，需要對各個徑的參數(shù)進行調(diào)整。該文利用衛(wèi)星信道的特點，提出了基于最大熵的盲分離算法，極大地減小了計算量。最后的仿真結果表明了算法有效性。

Abstract: 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 . -
