Digital Communications: Detectors and Estimators for the Time-Varying Channel with Intersymbol Interference.

Abstract

Receivers are designed for a pulse amplitude modulation digital communication system with additive white Gaussian noise and intersymbol interference. Considered along with the transversal filter receiver are the bit detector and block detector. The bit detector minimizes the probability of error in the decision on each data digit; the block detector minimizes the probability of error in making a joint decision on the entire sequence of data digits. The three receivers are compared in noniterative form on the fixed, known channel. The sampled autocorrelation function of the basic PAM pulse waveform determines the signal-space geometry and, along with the noise spectral density, the error probability of the three receivers. The output of a bank of matched filters, one matched to each translate of the basic PAM waveform, constitutes a sufficient statistic for the realization of all three receivers.
