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