Abstract
Teachings presented herein offer the performance advantages of sequence estimation for received signal symbol detection, while simultaneously providing potentially significant reductions in computational overhead. Initial demodulation of a received signal identifies a reduced number of candidate symbol values for all or a subset of a sequence of symbols represented in a received signal. A sequence estimation process, e.g., an MLSE process, constrains its state spaces to the reduced number of candidate symbols values, rather than considering all possible symbol values.
