The present disclosure relates generally to data decoding, and more particularly to non-binary iterative decoders. Non-binary LDPC codes and LDPC decoders that may be used to decode non-binary LDPC codes are disclosed. Systems and methods are also disclosed that compute messages related to non-binary LDPC codes, in a LLRV form and in a metric vector form and to process these messages in non-binary LDPC decoders. Systems and methods are additionally disclosed that convert messages between the LLRV form and the metric vector form. The implementation and use of non-binary low density parity check code decoders, the computation of messages in the LLRV and metric vector forms, and the use of message conversion systems and methods, according to this disclosure, may provide increased information relating groups of codeword bits, increased computational efficiency, and improved application performance.
