摘要：

Novel simplified merged processing element (SMPE) architectures to design a low-complexity successive-cancellation (SC) polar decoder are presented. The proposed SMPE architectures reduce the number of sign-magnitude conversions and switch networks, relative to those of the conventional merged processing element. Synthesis results show that the (1024, 512) SC polar decoder using the proposed SMPE architectures significantly decreases hardware complexity and improves technology scaled normalised throughput, as compared to those of the previously reported architectures.
