High-performance Parallel Concatenated Polar-CRC Decoder Architecture

초록

In this paper, a novel parallel encoding and decoding method is proposed, which uses concatenated polar-cyclic redundancy check (polar-CRC) codes for high throughput polar decoder implementation. When compared to previous works, the proposed method considerably reduces latency and improves throughput. A parallel concatenated polar-CRC decoder architecture based on the proposed method is presented and synthesized using 65-nm CMOS process technology. Synthesis results show that the proposed architecture has 4.9 times the data throughput and 4.5 times the hardware efficiency of conventional SC polar decoder architecture.
