| 摘 要： | 针对混迭矩阵发生突变的盲源分离（BSS）问题,提出一种基于二阶统计量的滑窗递归BSS方法。首先滑窗递归更新两个不同时延的自相关矩阵,然后结合幂迭代法和压缩处理在线计算矩阵束的广义特征向量以求得分离矩阵。与已有递归型盲源分离算法相比,该方法收敛速度快,追踪性能好,仿真结果验证了所提算法的有效性。

| Abstract: | A sliding window recursive blind source separation(BSS) algorithm for mixing matrix changed abruptly is presented.Firstly,two auto-correlation matrices with different time delay are estimated recursively.Secondly,the on-line calculation of the generalized eigenvectors,which is the column vectors of the desired separating matrix,is carried out by the power method and deflation procedure.Computer simulation results show that the proposed algorithm has faster convergence and better tracking performance than ex... |
