【摘要】：基于信道极化定理而提出的极化码是目前唯一被严格理论证明可以达到香农容量限的编码,并被接受为第五代移动通信系统(5G)中短码控制信道的编码方案。本文首先给出极化码的编码和译码原理,然后提出一种极化码与奇偶校验码级联的设计方案,发送端编码器采用奇偶校验码作为外码,极化码作为内码的级联编码结构。接收端译码器采用基于奇偶校验辅助的连续消除列表译码算法。相比于极化码与循环冗余校验码的级联方案,本文提出的级联设计方案具有更加优良的纠错性能,且没有提升编、译码的复杂度,有能力满足5G移动通信控制信道对纠错性能的要求。
[Abstract]:Polarization codes based on channel polarization theorem are the only codes which can reach Shannon capacity limit by strict theory. And it is accepted as the coding scheme of short code control channel in the fifth generation mobile communication system. Firstly, the encoding and decoding principle of polarization code is given in this paper. Then a design scheme of the concatenation of polarization code and parity check code is proposed. The transmitter encoder uses parity check code as the outer code. Polarization code is used as the concatenated coding structure of inner code. The receiver decoder adopts the algorithm of continuous elimination list decoding based on parity check. Compared with the concatenated scheme of polarization code and cyclic redundancy check code. The cascade design scheme presented in this paper has better error-correcting performance and does not raise the complexity of coding and decoding. It can meet the requirements of error-correcting performance of 5G mobile communication control channel.
