| 摘 要： | 为提高极化码的译码效率,文中提出了一种新颖的逐次抵消翻转(SCF)译码。与传统的SCF译码相比,其可以使用分布式CRC比特来降低计算复杂度。该译码通过提前终止对第一次SC译码的失败帧的译码,来减少信息比特的估计数量,同时尝试最小化附加的排序操作。仿真结果表明,与传统的SCF译码相比,该SCF译码将重复SC译码的计算复杂度至少降低了27%。

| Abstract: | In order to improve the decoding efficiency of polar codes, a novel Successive Cancellation Flip (SCF) decoding is proposed in this paper. Compared with traditional SCF decoding, it can use distributed CRC bits to reduce the computational complexity. The decoding reduces the estimated number of information bits by terminating the decoding of the failed frame of the first SC decoding in advance, while trying to minimize additional sorting operations. Simulation results show that compared with traditional SCF decoding, the SCF decoding reduces the computational complexity of repeated SC decoding by at least 27%. |
