Abstract
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
