Patent ID: 8605832

Claim:
A method, comprising: receiving, in a sequence estimation circuit, a sample of a received inter-symbol correlated (ISC) signal corresponding to a transmitted vector of L symbols, wherein L is a integer greater than 1, symbol L is a most-recent symbol of the transmitted vector, and symbol 1 is a least-recent symbol of the transmitted vector; generating a plurality of first candidate vectors, wherein: element L-m of each of the plurality of first candidate vectors holds one of a plurality of possible values of symbol L-m of the transmitted vector, elements L-m+1 through L of each of the plurality of first candidate vectors hold determined filler values, and m is an integer greater than or equal to 1; generating a plurality of metrics based on the plurality of first candidate vectors; and selecting, based on the generated plurality of metrics, a best one or more of the first candidate vectors.
