Maximum - Likelihood Seauence Estima tion of Digital Sequences i & he Presence of Intersymbo l Interference


A maximum-likelihood sequence estimator for a digital pulse-amplitude-modulated sequence in the presence of finite intersymbol interference and white Gaussian noise is developed. The structure cbm-prises a sampled linear filter, called a whitened matched filter, and a recursive nonlinear processor, called the Viterbi algorithm. The outputs of the whitened… (More)
