摘要/Abstract

摘要： 从滤波器组的角度出发,对多路复用通信方式进行了解释,同时给出了高斯加性白噪声情况下分析滤波器组的最优求解方法,通过该方法得到的分析滤波器组能够较好地跟踪输入信号的谱特性。

Abstract: All three types of transmultiplexer are explained from the view of filter banks.Addtionally,an optimal algorithm for the analysis filter banks is proposed under the environment of additive white Gauss noise (AWGN).The analysis filter banks derived from the algorithm can match the spectrum characteristics of the input siganls.

Key words: digital filter, transmultiplexer, multirate signal processing
