基于ICA Fixed-Point算法的信号图像分析

The ICA fixed-point algorithm and signal image analysis

从ICA算法的基准点出发,探讨了固定点算法中寻找W叠代公式的原理和方法,对分离一个独立成分和分离n个独立成分的运算方法进行了推导和分析;模拟试验表明:逐一分离的效果较好。

In this paper, a detailed analysis about the theory and iteration algorithms of the fixed - point ICA algorithm has been made. Two methods of the separation about one signal and the separation about n signals image were given. Simulation experiments showed that the method of separation one by one is better than the other.
