Abstract
An improved system and method for maximum likelihood sequence detection where an incoming stream of symbols subjected to intersymbol interference (ISI) are decoded without knowledge of channel coefficients. Through use of improved metrics, the Fano and stack algorithms may be employed to determine the maximum likelihood sequence detection for a given input data stream during blind equalization, offering improved performance over the Viterbi algorithm which requires foreknowledge of the channel coefficients to operate effectively.
