Design of low latency successive cancellation decoder for polar codes
Zheyan Piao, Jin-Gyun Chung · 2016
Polar codes have recently become increasingly popular due to their simple structure and low decoding complexity. However, polar codes are still not suitable for real-time applications because of the long decoding latency. In this paper, by analysis of the conventional architecture of SC decoder, a low latency SC decoder architecture is proposed. Using the proposed architecture, the decoding latency can be reduced by 25% compared with conventional architectures.
