| 摘 要： | 研究了基于定向天线的多中继节点放大转发协同通信技术。首先，从理论上推导了全向发送全向接收（without beamforming transmit receive, N-BF)，定向发送全向接收(beamforming transmit-without beamforming receive, T-BF)以及定向发送定向接收(beamforming transmit-beamforming receive, TR-BF)3种模式下信道容量及其中断概率。然后，结合具体的数值仿真对不同模式下的信道容量和中断概率分别进行了详细的分析比较。结果表明，TR-BF性能最优，TR-BF以及T-BF相比N-BF而言，系统受噪声影响更小。

| Abstract: | Directional antenna based multi-relays amplify-and-forward(AF) cooperative communication technology is studied. Firstly, the channel capacity and outage probability of three modes, which include without beamforming transmit receive(N-BF), beamforming transmit-without beamforming receive (T-BF) and beamforming transmit-beamforming receive (TR-BF), are theoretically derived. Secondly, the channel capacity and outage probability of different modes are respectively analyzed in detail combined with the specific numerical simulation. Finally, simulation shows that the TR-BF has the best optimal performance, the TR-BF and T-BF are less affected by noise than N-BF. |
