This paper presents two low-complexity reliability-based message-passing algorithms for decoding LDPC codes over non-binary finite fields. These two decoding algorithms require only finite field and integer operations and they provide effective trade-off between error performance and decoding complexity compared to the non-binarysumproductalgorithm. They are particularly effective for decoding LDPC codes constructed based on finite geometries and finite fields.
