一种新的非线性函数的Fast-ICA盲源分离

Blind source separation using Fast-ICA with a novel nonlinear function

Pengfei Xu, Yinjie Jia, Zhijian Wang

摘要:

盲源分离是信号处理中的一个研究热点,而独立分量分析是解决盲源分离问题的一个非常有效的工具。为了改善分离性能,引入了一个新的非线性函数sin。它可以代替常用的经典函数(tanh,gauss和pow 3),不需要根据信号的高斯特性选择不同的非线性函数。两次Matlab仿真结果表明,改进后的Fast-ICA算法不仅提高了分离精度,而且加快了盲源分离的收敛速度。

英文摘要:

Blind source separation(BSS) is a hotspot in signal processing, and independent component analysis (ICA) is a very effective tool for solving the BSS problem. In order to improve the performance of the separation, a new nonlinear function sin was introduced. It can replace the commonly used classical functions (tanh, gauss and pow3) and does not need to select different nonlinear functions according to the Gauss property of signals. The two Matlab simulation results show that the improved Fast-ICA algorithm with the proposed nonlinearity can not only improve the separation accuracy but also speed up the convergence of blind source separation.
