| 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.

| Abstract: | Based on the idea of hypercube constellation 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 transmission in wireless communication.The performance of system with different relay-codes 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 performance 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 constellation has advantage on additional complexity when some condition is satisfied. |
