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。
The FIR (WFIR) transversal filter based on wavelet transform is studied to deal with the transducer equalization. The WFIR coefficients are constructed by LMS adaptive algorithm. Experiments show that compared with the traditional FIR and IIR structure equalizers, the proposed method has the advantages of good balance and low computational load.
