抄録(和) Channel polarization and Polar code are widely considered as major breakthroughs in coding theory because they have shown promising features for future wireless standards. The main drawbacks of Polar code are high-latency in decoding hardware, and unimpressive error-correction performance in case limited code-length is implemented. These two disadvantages limit implementation of Polar code in low-throughput wireless communication systems. In this paper, we propose a low-complexity low-latency hardware architecture for the soft-decision compact (16,11) Systematic Successive Cancellation Polar Decoder (S-SCD). Experimental results has shown that the latency of the proposed S-SCD improves 3.75 times and 2.75 times compared with conventional and 2b-SC architectures. Besides, it has also shown a better BER/FER performance compared with RS(15,11) code, which is applied widely in current VLC-based systems.
