Abstract :
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 soft decisions from the channel are available.
