The recent Digital Video Satellite Broadcast Standard (DVB-S2) has adopted a powerful FEC scheme based on the serial concatenation of Bose-Chaudhuri-Hocquenghen (BCH) and low-density parity-check (LDPC) codes. The high-speed requirements, long block lengths and adaptive encoding defined in the DVB-S2 standard, present complex challenges in the design of an efficient codec hardware architecture. In...
Due to their excellent bit-error-rate performance, low density parity check codes (LDPC) have been adopted by the recent digital video satellite broadcast standard (DVB-S2). In order to simplify the encoding procedure, irregular repeat and accumulate (IRA) LDPC codes have been chosen. This paper proposes an efficient, low delay and high throughput encoder architecture shared by all DVB-S2 LDPC-IRA...
