在无线Mesh网络和蜂窝系统中，协作中继作为一种提高传输质量的方法已经被研究。源节点上的多个天线单元实现了自适应波束形成，从而提高了中继传输的总体性能。针对MISO-SISO/MIMO-MIMO直接链路放大转发中继，当源节点具有两个或多个天线单元且知道所有信道信息时，提出了在源节点进行简单的发射波束形成，并对误包率进行了评估。仿真结果表明，该方法具有较低的复杂度和较高的性能。
A cooperative relay has been studied as a method to improve transmission quality in wireless mesh networks and cellular systems. Multiple antenna elements at a source node enable adaptive beamforming and thus improve total performance of relay transmission. In this paper, we propose simple transmit beamforming at a source node when the source node has two or more antenna elements and knows all channel information in MISO-SISO/MIMO-MIMO amplify-and-forward relays with direct link and evaluate the packet error rate. The simulation results show that the proposed method achieves both low complexity and high performance.
