摘要：

Information, signal amplitude and phase change drastically in broadband multimedia communications and broadcasting. Channel coding is a key technology to ensure reliable information transmission in broadband mobile multimedia communication system. Polar codes are the first channel codes that can be proved to achieve channel capacity. In this paper, we propose a fast simplified multi-bit successive cancellation list (Fast-SMSCL) decoding method for polar codes. In our proposed Fast-SMSCL decoding, we take fully use of consecutive information bits and achieve prominent latency reduction of 3% to 58% compared to the existing simplified multi-bit successive cancellation list decoding. In addition, we also propose an architecture of Fast-SMSCL decoder, especially path memory unit and partial sum network. Finally, we implement the decoder on FPGA which achieves high throughput of 125Mbps.
