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(More)
Because of its excellent bit-error-rate performance, the Low-Density Parity-Check (LDPC) decoding algorithm is gaining increased attention in communication standards and literature. Also the new Chinese Digital Video Broadcast standard (CDVB-T) uses LDPC codes. This standard uses a large prime number as the parallelism factor, leading to high area cost. In(More)
The decoding of Turbo encoded signals (" Turbo decoding ") is a computa-tionally very intensive process. In 1998, Frey and Kschischang published a method called " early detection, " in which bits in the trellis or segments of the trellis that have become certain, are no longer processed. Also known are a few varieties of window based Soft Input Soft Output(More)
