Abstract

This paper exploits the similarity between the two stages of belief propagation decoding algorithm for low density parity check codes to derive an area efficient design that re-maps the check node functional units and variable node functional units into the same hardware. Consequently, the novel approach could reduce the logic core size by approximately 21% without any performance degradation. In addition, the proposed approach improves the hardware utilization efficiency as well.
