摘要
研究了基于小波变换的FIR(WFIR)横向滤波器进行换能器均衡的处理方法,并以LMS自适应算法构造WFIR系数。实验表明;与传统的FIR及IIR结构均衡器相比,该方法具有均衡效果好、计算量小的特点。
This paper introduces transducer equalization method using wavlet transform based FIR (WFIR) transversal filter, and employing LMS adaptive algorithm to construct WFIR filter's weights. Experimelit shows that: compared to traditional FIR and IIR mode equalization, this method can get better equalization results while keeping low computational burden.
