Abstract:
An LDPC decoder receives channel information and performs a bit flipping algorithm to correct unsatisfied checks with respect to a parity matrix H. The threshold condition for determining whether to flip a bit is a function of the channel information itself. A threshold Thk used to evaluate the threshold condition may vary between iterations based on the number of iterations, number of bits flipped in the previous iteration, and number of unsatisfied checks. A threshold Thki may be calculated for each bit position. Thki and the threshold condition may be a function of whether bit position i was flipped in a previous iteration. A binning approach for parameters of the threshold condition may be used to reduce hardware complexity.
