Two-Bit Bit Flipping Algorithms for LDPC Codes and Collective Error Correction

A new class of bit flipping algorithms for low-density parity-check codes over the binary symmetric channel is proposed. Compared to the regular (parallel or serial) bit flipping algorithms, the proposed algorithms employ one additional bit at a variable node to represent its "strength." T...
