摘要
非线性自适应IR滤波器的组合梯度算法朱幼莲张玲华(常州技术师范学院,常州213001)(南京邮电学院,南京210003)在自适应滤波中,线性滤波器因其本质的简单性而广为应用.但是,在非高斯和高斯背景下的最优滤波是非线性的,非线性自适应滤波器常具有比...
A new composite gradient algorithm (CGA) of nonlinear adaptive IIR filters (NAIIRF) is presented. It does not need stability monitoring in the adaptive process. NAIIRF using CGA can reach the global optimization of objective function and quickly convergent. Experimental results show that CGA has higher convergence performance as compared with other algorithms.
