Abstract :
Communication systems that transmit samples from analog waveforms are considered. Optimum pre- and postfilters of these samples are derived. The criterion of optimality is minimization of the mean-square error in reproducing the waveforms subject to a constraint on the signal-to-noise ratio per transmitted sample. The results of this filtering are evaluated and compared to other filtering schemes.
