Patent ID: 8910023

Claim:
An apparatus, comprising: 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); a reliability memory configured to store one or more known LLRs, wherein the known LLRs are stored in the reliability memory prior to the soft decoder receiving the signal to be decoded; and a controller configured to: repetitively and selectively provide the soft decoder with known LLRs chosen from the reliability memory, control the soft decoder to decode the signal, and when the soft decoder fails to decode the signal with the known LLRs: to compute one or more new LLRs; to repetitively and selectively provide the soft decoder with the new LLRs; and store the new LLRs as known LLRs in the reliability memory upon determining that the soft decoder successfully decoded the signal with the new LLRs.
