Abstract

Because of its excellent bit-error-rate performance, the Low-Density Parity-Check (LDPC) algorithm is gaining increased attention in communication standards and literature. The new Digital Video Broadcast via Satellite standard (DVB-S2) is the first broadcast standard to include a LDPC-code, and the first implementations are available. In our investigation of generic LDPC-implementations we found that scalable sub-block parallelism enables efficient implementations for a wide range of applications. For the DVB-S2 case, using sub-block parallelism we obtain half the chip-size of known solutions. For the required performance in the normative configurations for the broadcast service (90 Mbps), the area is even 1/3 compared to the smallest published decoder.
