摘要

本文提出了一种利用多速率滤波器组消除码间干扰的预编码方案。ISI信道可能没有逆，例如频率选择性衰落信道。从FIR ISI传递函数的零集出发，给出了线性FIR理想均衡器存在的充分必要条件。该条件易于检查和满足。本文还介绍了前编码和后编码的设计。最后给出了一个数值算例来说明该理论。

A new precoding for ISI cancellation using multirate filterbanks

In this paper, we propose a new precoding scheme for intersymbol interference (ISI) cancellation using multirate filterbanks. The ISI channel may not have inverses, such as frequency-selective fading channels. We present a necessary and sufficient condition on an FIR ISI transfer function in terms of its zero set such that a linear FIR ideal equalizer exists. The condition is easy to check and satisfy. Designs of pre/postcodings are also presented. A numerical example is presented to illustrate the theory.
