摘　　要：基于多维映射和编码理论的基本思想,设计了两种适应多用户单中继模型的中继编码矩阵,为无线通信中增强中继传输性能提供了良好的解决方案.推导了两种中继编码系统的性能,与未进行中继编码的系统进行性能仿真对比,结果表明两种中继编码均可以获得额外的增益,而基于编码理论的中继编码更具性能优势.分析了中继编码系统相对于未编码系统所带来的额外复杂度,分析表明满足一定条件下,基于多维映射的中继编码在额外复杂度方面具有优势.Based on the idea of hyperube comteUafion and code theory, two kinds of relay-coding matrix are designed for multi-user single relay model, that provide the schemes for resolving how to enhance the performance of relay tmnsnfission in wire less communication. The performance of system with different relay-cedes are deduced, compared with the system without relay codes through simulation,the result shows that additional gain can be achieved and the relay-code based on code theory has perfor mance advantage. Compared with system without relay-code, the additional complexity of two relay-coded systems are analyzed. The analysis result shows that the relay-code based on hypercube comtellation has advantage on additional complexity when some condi- tion is satisfied.
