Applications of nonmaximally decimated multirate filterbanks in partial response channel ISI cancellation
Xiang‐Gen Xia · 1996
We study applications of nonmaximally decimated multirate filterbanks (NMDMF) in partial response channels, where the partial response transfer functions may not have inverses, such as frequency-selective fading channels. The NMDMF plays the preprocessing (or precoding) role. We present a necessary and sufficient condition on an FIR channel transfer function in terms of its zero set such that an FIR NMDMF with N channels and decimation by K, 0<K
