Abstract
A technique for decoding low-density parity check codes includes performing a combined check node and variable node calculation. Decoding is initialized using channel likelihood values estimated from a received physical signal. The decoding iteratively updates the variable nodes. Performing a combined check node and variable node calculation can enable reduced memory usage and faster convergence for the decoder.
