Abstract
A novel modification is introduced in this paper for the belief propagation decoder of polar codes, wherein adjacent two processing stages are efficiently combined together to speed up decoding. Corresponding path based belief estimation method is presented in detail. The proposed decoder halves the number of stages of the conventional decoder and thus can significantly reduce the decoding latency and lower message memory requirement.
