Abstract
An adaptive maximum likelihood sequence estimator includes a channel estimator and a Viterbi algorithm processor for estimating the maximum likelihood transmission symbol sequences. The algorithm processor includes a branch metric computer in which common components are found from regularity in computations of coded alphabets of the transmission symbols and are used for all branch metric computation to reduce the total amount of the operations. Such effective computations are implemented by either of hardware and software in accordance with the constitution of the system of the adaptive maximum likelihood sequence estimator.
