Abstract
A receiver and method for HARQ combining of a received codeword in a receiver with a FEC decoder, the method including computing Log Likelihood Ratios (LLRs) of demodulated soft symbols of the received codeword and outputting the LLRs as a-priori soft bits; performing iterative decoding of the a-priori soft bits in a Forward Error Correction (FEC) decoder; outputting a posteriori soft bits of the a priori soft bits of the received codeword from the FEC decoder; and HARQ combining the a posteriori soft bits with a retransmission of the received codeword.
