摘要：
In this paper, the dual coupled polar(DC-Polar) code is proposed and its lower bound is derived. Based on this, DC-Polar code combined with bit-interleaved coded modulation (BICM) is presented for high-order constellations. To overcome the rate matching problem, a new coded modulation scheme called DC-Polar two-layer coding (DC-Polar-TLC) is proposed. The advantage of this scheme is that the code length can be adjusted flexibly without applying puncturing or shortening methods. It is shown by numerical simulations that the proposed DC-Polar-TLC scheme has good performance. The presented scheme can achieve about 0.6 dB performance gains compared to the bit-interleaved coded modulation scheme with CRC-aided polar code for the case of 64QAM. © 2022 Chinese Institute of Electronics.
