Two-bit message passing decoders for LDPC codes over the binary symmetric channel

Two-bit message passing decoders for LDPC codes over the binary symmetric channel

A class of two-bit message passing decoders for decoding column-weight-four LDPC codes over the binary symmetric channel is proposed. The thresholds for various decoders in this class are derived using density evolution. For a specific decoder, the sufficient conditions for correcting all error patt...
