摘要

BP algorithm is one of the most prominent decoding algorithms based on message passing. However, it is not commonly adopted in hardware implementation for the high computational complexity. The normalized min-sum (NMS) algorithm was then proposed to solve this problem but with performance flaws. To satisfy the comprehensive requirements of complexity and accuracy in 5G systems, we introduce an app...
