An approach is provided for efficiently decoding low density parity check (LDPC) codes. An LDPC decoder (305) includes a memory (901, 1101) for storing a mapped matrix that satisfies a plurality of parallel decodable conditions for permitting a lumped memory structure (901, 1101). Additionally, the decoder (305) includes a parallel processors (903, 1103) accessing edge valves from the stored mapped matrix decode the LDPC codes. The above approach has particular applicability to satellite broadcast systems.
