Patent abstract
A decoder for decoding low-density parity-check codes includes a first calculator that calculates ιιrRml, for each parity check equation, at iteration i−1. A second calculator calculates ιιrQιm, for each parity check equation, at iteration i. ιιrQιm represents information from bit node I to equation node m, one for each connection. ιιrRml represents information from equation node m to bit node I, one for each connection. The first calculator is responsive to the second calculator.
