Pilot symbol-aided sequence estimation for highly-spectrally-efficient communications

摘要

A receiver may be operable to generate, utilizing a sequence estimation process, estimates of transmitted symbols which may comprise information symbols and one or more pilot symbols. For each of the information symbols, a corresponding one of the generated estimates may be selected from a first set of one or more values based on a search. For each of the one or more pilot symbols, a corresponding one of the generated estimates may be selected from a second set of one or more values based on a predetermination. The second set of one or more values may comprise one or more symbol values predetermined as corresponding to the one or more pilot symbols. Each of the values in the second set may comprise a known value in a modulation symbol constellation associated with the information symbols. Power of each of the one or more pilot symbols may be zero power.
