摘要：A wireless communications device includes a receiver, and a decoder coupled
downstream from the receiver and using a modulation having memory for a receivedsignal and to decode the received signal. The decoder decodes the received signal by atleast determining a channel estimate for the received signal, generating partial sumtables based upon the channel estimate and possible values of a transmitted signal,correlating actual values of the received signal to the possible values from the partialsum tables to generate branch metrics associated with the modulation, anddemodulating the received signal based upon the branch metrics using an iterativeprocess based upon exchanging extrinsic information with an outer forward errorcorrection (FEC) code.
