List-Pruning SCL Decoder for Polar Codes Using Parity-Check Bits

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose encoding and decoding algorithms of polar codes which add pruning bits into the transmitted information so as to satisfy parity check condition.
The proposed algorithm can reduce the list size during successive cancellation list decoding using pruning bits.
We formalize the optimization problem using the bit error rate of each bit obtained by the Gaussian approximation and determine the position of the pruning bit so that both decoding performance and list reduction performance are maximized.
Our proposed algorithm can reduce the list size during successive cancellation list decoding without sacrificing error correction performance.
Moreover, we apply the proposed method to irregular polar codes.
