| 摘 要： | 针对使用单个中继节点的多输入多输出（MIMO）中继系统，以极大化接收端各子流的最小信噪比为目标，提出一种线性收发机设计方案。在此方案中，系统中的各节点沿着对应信道的特征方向进行线性信号处理，使等效的MIMO信道被分解为一组并行的高斯信道。通过优化理论，证明了在中继节点处最优的功率分配，应使接收端各子流具有相同的信噪比。

| Abstract: | A linear transceiver design method is proposed to maximize the minimal signal-to-noise ratio（SNR） of all sub-streams in MIMO single-relay system. In the proposed strategy, all nodes per- form linear processing along the eigenvectors of the corresponding channel matrix, and the equivalent MIMO channel is then decomposed into a set of parallel Gaussian channels. According to optimization theory, it is proved that the optimal relay-power allocation can be get from equal SNR of all substreams at the receiver. |
