Zero-forcing equalizability of FIR and IIR multichannel systems with and without perfect measurements
Er‐Wei Bai, Zhi Jun Ding · IEEE Transactions on Communications · 2000
We study the linear zero-forcing equalizability of a communication channel. Necessary and sufficient conditions are given in terms of the zeros of the transfer function. Detailed procedures of equalizer design for minimum sensitivity with respect to modeling errors and white noise are also presented. It is found that the worst case effect of channel mismatch on the performance may be modeled as equivalent losses in signal-to-noise ratio.
