Overlapped message passing technique with resource sharing for high speed CMMB LDPC decoder.

The article presents a study which explores an overlapped message passing (OMP) technique with resource sharing for high speed China multimedia mobile broadcasting (CMMB) low-density parity-check (LDPC) decoder. The study proposed a novel OMP algorithm to find the permuted parity check matrix of the CMMB. Results show that pipelining performance could be up to by 45.
