摘要：

This paper deals with reduced-complexity NBLDPC check node implementation based on the Extended MinSum algorithm. We propose to apply a recently introduced presorting technique to the forward-backward architecture. The presorting of the check node inputs allows for significant complexity reduction. Simulation and synthesis results showed that this approach does not introduce any performance loss and can lead to significant area reduction in FPGA implementations (up to 54% for high check node degrees).
