Abstract
Configurable permutators in an LDPC decoder are provided. A partially-parallel architecture combined with the proposed permutators is used to mitigate the increase in implementation complexity for the multi-mode function. To overcome the difficulty in efficient implementation of a high-throughput decoder, the variable nodes are partitioned into several groups, and each group is processed sequentially in order to shorten the critical-path delay and, hence, increase the maximum operating frequency. In addition, shuffled message-passing decoding can be adopted in decoders according to the invention to increase the convergence speed, which reduces the number of iterations required to achieve a given bit-error-rate performance.
