Abstract:

It is shown that the maximum-likelihood ML detector for noisy, binary channel with restricted intersymbol interference ISI consists of a matched filter followed by a tapped delay line. The useful output is a nonlinear function of the tap outputs. Bounds on the per-symbol probability of error indicate that a gross approximation to the ML detector performs as well as an optimum linear detector. The major assumptions are 1 bi-polar binary signals, 2 ISI only between adjacent bauds, 3 stationary additive white, Gaussian noise, and 4 perfect synchronization. Extensions are suggested to remove assumptions 1 and 2 and to handle stationary, non-white Gaussian noise. Author
