Low density parity check (LDPC) decoder with reduced complexity

Abstract

The present disclosure relates to a method and a receiver device configured to implement a low density parity check (LDPC) decoder with reduced complexity. The method may include performing a first set of decoding iterations on an encoded codeword received in a transmission from a transmitter. If the first set of decoding iterations fails to successfully decode the encoded codeword, the method may further include performing a second set of decoding iterations on the encoded codeword, where the second set of decoding iterations performs a check node update on a set of partial check nodes of the matrix. If the second set of decoding iterations derives a decoded codeword, a network operation based on the decoded codeword may be performed.
