Claim One:
1. A method, in a communications receiver, the method comprising: in a first decoding iteration for a series of received unknown information symbols, generating a plurality of soft bits and corresponding probability metrics, the plurality of soft bits corresponding to the series of received unknown information symbols; regenerating estimates of the received unknown information symbols as a function of the soft bits and corresponding probability metrics; calculating an estimate of the average amplitude of the received unknown information symbols, or calculating an estimate of the propagation channel response experienced by the received unknown information symbols, or both, as a function of the regenerated estimates of the received unknown information symbols; applying the calculated estimate of the average amplitude of the received unknown information symbols, or the estimate of the propagation channel response, or both, to produce demodulated symbols for a second decoding iteration for the series of received unknown information symbols.
