| 摘 要： | 把似P范数FOCUSS方法应用于稀疏信号盲分离中,采用k均值聚类算法来估计混合矩阵;然后利用似P范数FOCUSS方法来求解具有线性约束优化问题的稀疏源信号,从而给出了一种基于似P范数FOCUSS方法的稀疏信号盲分离算法。该算法计算量小,精度较高。仿真结果表明该算法是有效的,具有良好的分离性能。

| Abstract: | In this paper,we propose a blind sparse source separation algorithm by using P-norm like diversity measure of FOCUSS.The proposed algorithm first estimates the mixied matrix by using the k-means clustering algorithm.Then P-norm like diversity measure of FOCUSS is applied to the linearly constrained optimization problem for recovering the sparse sources.Finally,a blind Sparse Source Separation Based on P-norm like diversity measure of FOCUSS algorithm is obtained.The presented algorithm is characterized by high accuracy and less computation.Simulation results illustrate the efficiency and the good performance of the algorithm. |
