Executive Summary

Low-Density Parity-Check (LDPC) code is an Error Correcting Code (ECC) which is used in high throughput applications such the Digital Video Broadcasting for the second generation digital satellite and terrestrial television broadcasting system (DVBS2), (DVB-T2). The LDPC codes can be efficiently decoded with the original Belief-Propagation (BP) algorithm or the Sum-Product Algorithm (SPA). The BP algorithm is recognized by its good error correction performance but needed many multiplications to update the check and variable nodes which make it difficult to use for efficient hardware implementation.
