摘要

对并行次成分提取算法在信号特征提取中实现方向收敛的过程进行了研究。采用比较未加权的PAST次子空间跟踪算法和加权的PAST并行次成分提取算法，分析加权规则对次成分提取算法方向收敛行为的限定方式。理论分析表明，加权规则对状态矩阵的各个向量和次成分之间的角度限定存在规律，并给出了加权规则对状态矩阵各个向量方向的作用方式和定理和讨论。最后，Matlab仿真实验验证了理论分析的结果。

Abstract

The extraction of parallel minor components algorithm in directional convergence in signal feature extraction was studied.By comparing the unweighted projection approximation subspace tracking (PAST) algorithm with the weighted PAST parallel minor component extraction algorithm

the evolution method of the minor component extraction algorithm was analyzed.Theorical analysis illustrated that the weighted rule was able to guide the angle evolution between the vectors of the state matrix and minor components.Finally

Matlab simulation verifies the validity of the proposed theory.
