Multi-rate polar codes for solid state drives

Yi Zhong, Chun Zhang, Chenrong Xiong, Zhiyuan Yan

ICASSP 2017accepted

As solid state drives (SSDs) are gradually replacing hard disk drives, error correction is critical to SSDs since NAND flash has deteriorating reliability over their life span. Existing error correction codes suffer from limited error correction capability or error floor issues. Polar codes are prom…

Error performance analysis of the symbol-decision SC polar decoder

Chenrong Xiong, Jun Lin, Zhiyuan Yan

ICASSP 2016accepted

Polar codes are the first provably capacity-achieving forward error correction codes. To improve decoder throughput, the symbol-decision SC algorithm makes hard-decision for multiple bits at a time. In this paper, we prove that for polar codes, the symbol-decision SC algorithm is better than the bit…
