摘要:

提出了一种小波变换空域相关的信息极大化独立分量分析（ICA）超分离方法，并将其应用于多跳频信号的盲分离和参数估计中。理论分析及仿真结果表明，空域相关的ICA方法相对传统的ICA方法可较好地用于多跳频混合信号的分离与参数估计，且具有更快的收敛速度、无需多导信号即可求出解混矩阵、抗噪能力强等优点。

Abstract:

A novel method of spatialcorrelation based independent component analy sis(ICA) using infomax algorithm is proposed and applied in the blind separati on and estimation of multiple frequency hopping(FH) signals. Simulation results show the proposed method posesses excellent features in faster convergence rate compared with traditional algorithm,can extract unmixing matrix without multi path signals,and has high antinoise performance.
