| 摘 要： | 为了提高协作通信系统的频谱效率和中断性能,给出了解码转发协议下的两路中继协作通信系统的模型。在该模型下,提出了两种数据传输模式,并分析了该两种数据传输模式的中断概率性能,推导了中断概率闭式结果及分集增益和复用增益之间的关系。仿真结果显示,与传统的两中继解码转发协议相比,两种传输模式的中断概率性能都有较大的提高。 |

| Abstract: | In order to improve the spectral efficiency and outage performance of the cooperative communication system,a Two-Path Relaying(TPR) cooperative communications model based on the Decode-and-Forward(DF) protocol was proposed.Meanwhile,two data transmission modes were presented for the proposed system.The closed-form expressions for outage probability and the relations between diversity gain and multiplexing gain were derived.The simulation results show that,compared with the conventional two-relay DF protocol,the outage probability performance of the two proposed transmission models is greatly improved. |
| Keywords: | cooperative communication Decode-and-Forward(DF) outage probability Diversity-Multiplexing Tradeoff(DMT) Rayleigh fading |
