| 为解决当前5G信道安全编码方案中存在的编码复杂、传输性能较差及数据冗余度高的不足，提出了一种基于超基性机制的5G网络信道安全编码方案。首先，利用5G信道编码过程中的极化序列具有的正交特性，通过模二运算和张量积运算来实现序列特征矢量的极化分割，有效降低5G信道编码过程中冗余比特数量，高效调度传输序列，提升网络信道安全编码效率。随后，考虑5G信道矫正比特序列具有的极化性质，通过正交权向量映射方法，设计二次编码极化方法，用于降低信道预发射过程中存在的冗余码元数量，改善码元拥塞现象，提高信道发射效率，具有较高的信道码元基性极化率。仿真实验表明：与当前常用的时间片分支累积算法（Time Slice Branching Accumulation，TSB算法）、信道最低分割度编码算法（Channel Minimum Segmentation Coding Algorithms，CMSC算法）相比，本文算法具有数据传输带宽高、时间片误比特数低、编码速率快、周期重传次数少等特性，具有很强的实践部署价值。 |

| In order to solve the problems of large coding complexity, poor transmission performance and high data redundancy in current 5G channel security coding schemes, a new channel security coding scheme for 5G network based on super-basic mechanism is proposed. Firstly, by using the orthogonal property of polarization sequence in 5G channel coding process, polarization segmentation of sequence feature vectors is realized by modular binary operation and tensor product operation, which can significantly reduce the number of redundant bits in 5G channel coding process, efficiently schedule transmission sequence and improve the efficiency of network channel secure coding. Then, considering the polarization property of 5G channel correction bits, the algorithm designs a quadratic coding polarization method by orthogonal weight vector mapping, which is used to reduce the number of redundant symbols and improve symbol congestion during channel pre-transmission. It improves the channel transmission efficiency and has a high fundamental polarization of channel symbols, and can meet the needs of UWB transmission of 5G data. The simulation results show that compared with the current time Slice Branching Accumulation algorithm and Channel Minimum Segmentation Coding Algorithms algorithm, the proposed algorithm has the characteristics of higher data transmission bandwidth, lower time slice error bits, fast coding rate and less periodic retransmissions. It has strong practical deployment value. |
