SOFT DECODING FOR QUANTIZIED CHANNEL

Systems, methods, and other embodiments associated with soft decoding for a quantized channel are described. According to one embodiment, an apparatus includes a soft decoder configured to decode a signal received from a quantized channel based, at least in part, on one or more log likelihood ratios (LLRs). The apparatus may also include a reliability memory configured to store one or more known LLRs, and a controller configured to repetitively and selectively provide the soft decoder with known LLRs chosen from the reliability memory, to control the soft decoder to decode the signal, and to selectively update the reliability memory upon determining that the soft decoder successfully decoded the signal.
