摘要
针对传统的滤波方法对混合噪声滤除性能不足的问题,提出一种针对混合噪声的基于Volterra 级数的非线性滤波方法,采用蝙蝠算法对Volterra滤波器的核参数进行优化。仿真实验结果表明,经蝙蝠算法优化核参数的非线性Volterra滤波器能够较传统滤波方法有效滤除混合噪声,信号失真现象不明显,同时其运算量小的特点较传统滤波方法具有更好的实时性。
Aiming at the problems of the bad filter performance for mixed noise in traditional filter method,a nonlinear filte ring method based on Volterra series was proposed,the kernel parameters of Volterra filter were optimized by bat algorithm.The simulation results show that nonlinear Volterra filtering with kernel parameters optimized by bat algorithm can more effectively fil ter mixed noise than traditional filter,the distortion of output signal was not obvious,and the new filtering method with less calcu lated amount was more real time than traditional filter method.
