Abstract
This paper presents a reduced complexity Viterbi algorithm for use as sequence estimator for linear intersymbol interference channels with c oarsely located coefficients. In particular, the complexity does not d epend on the channel impulse response length but only on the number of nonzero coefficients. No approximations are used in the algorithm.
