Abstract [en]

Low-density parity-check codes have recently received extensive attention as a forward error correction scheme in a wide area of applications. The decoding algorithm is inherently parallelizable, allowing communication at high speeds. One of the main disadvantages, however, is large memory requirements for interim storing of decoding data. In this paper, we propose an architecture for an early decision decoding algorithm. The algorithm significantly reduces the number of memory accesses. Simulation results show that the increased energy dissipation of the components is small compared to the reduced dissipation of the memories.
