【摘要】：编码协作通过将虚拟MIMO传输和信道编码相结合,在取得分集增益的同时实现了前向纠错,是5G通信中极具应用前景的技术。由于Polar码是目前唯一的理论上可达到香农限传输的信道编码技术,成为编码协作中具体编码技术的优选。为提出衰落信道下高增益的Polar码编码协作方案,从分码字构造方式、性能优化等方面对基于Polar码的编码协作进行了研究,提出了基于Plotkin构造和信息位重休眠的Polar码编码协作方法。仿真结果表明,在慢衰落信道下,所提方法对256码长、0.25码率的Polar码性能有不同程度的提升。
[Abstract]:Coding collaboration combines virtual MIMO transmission with channel coding to achieve diversity gain while achieving forward error correction. It is a promising technology in 5G communication. As Polar code is the only channel coding technology that can reach Shannon limit transmission theoretically, Polar code is the best choice of specific coding technology in coding collaboration. In order to propose a high gain Polar code coding cooperation scheme in fading channel, the coding cooperation based on Polar code is studied from the aspects of code division construction, performance optimization and so on. Based on Plotkin construction and information bit rehibernation, a Polar code coding cooperation method is proposed. The simulation results show that the proposed method can improve the performance of 256-bit / 0.25 bit rate Polar code in slow fading channel.
