脉冲噪声环境下基于最大相关熵准则的仿射投影算法
Affine proj ect algorithm based on maximum correntropy criterion for impulsive noise environment
摘要
Abstract
In many engineering applications,noise often shows strong impulsive,and is represented by a stable distribution model in mathematics.Traditional adaptive filtering algorithm is not robust in stable distribution noise.Maximum correntropy criterion can effectively improve the performance of the adaptive filtering algorithm under impulsive noise conditions.Applying symmetricαstable noise as the impulsive noise model,maximum correntropy criterion as the cost function,an affine proj ect algorithm based on maximum correntropy criterion is proposed.By using a prior error as independent variable in the correntropy function,the improved affine proj ect algorithm obtains a good convergence effect in impulsive noise environment.Experimental results show that the new algorithm has good convergence speed and performance under strong impulsive noise and low generalized signal-to-noise ratio conditions.关键词
