摘要

A very fast quantised belief propagation algorithm is proposed for decoding low-density parity-check codes. This algorithm enables flexible quantisation schemes with low complexity and good performance near to or even better than that of continuous decoding. It can lower the error floor at high signal-to-noise ratios.
