NYQUIST'S PROBLEM IN PULSE TRANSMISSION THEORY,

Abstract

The problem, posed by Nyquist, of jointly optimizing the transmitter and receiver in a pulse amplitude modulation system is reformulated and analyzed in some detail. Nyquist's problem has not been completely solved in this report. The main results are that, using a mean square criterion, the optimum receiver for each message value can be represented as a matched filter followed by a tapped delay line and a sampler. The optimum tap gains are unique, and formulas are given for this set of gains and for the associated value of the mean square error. (Author)
