We design systematic and regular repeat-accumulate (RA) codes for non-ergodic block-fading channels. An encoder structure of RA codes for block-fading channels with an arbitrary number of fading blocks is proposed. Simulation results show that the proposed RA codes achieve full-diversity word error rate (WER) performance over block-fading channels. In(More)
Binary message-passing (BMP) decoders for root-low-density parity-check (LDPC) codes over block fading channels (BFC) are studied using density evolution (DE) and outage boundary analysis. A-priori channel estimation techniques suitable for root-LDPC code are proposed based on DE. The results show that BMP decoders can achieve full diversity performance if(More)
