论文摘要
我们提出了一种贪婪的最小平方误差（MMSE）的天线选择算法，用于放大和前向（AF）多输入多输出（MIMO）继电器系统。假设在多流数据之间进行平等功率分配，我们将添加每个附加天线对产生的平方平方误差（MSE）的封闭形式表达式（MSE）。基于此结果，我们迭代地选择继电器节点处的天线对，以最大程度地减少MSE。仿真结果表明，我们的算法大大胜过现有方案。
We propose a greedy minimum mean squared error (MMSE)-based antenna selection algorithm for amplify-and-forward (AF) multiple-input multiple-output (MIMO) relay systems. Assuming equal-power allocation across the multi-stream data, we derive a closed form expression for the mean squared error (MSE) resulted from adding each additional antenna pair. Based on this result, we iteratively select the antenna-pairs at the relay nodes to minimize the MSE. Simulation results show that our algorithm greatly outperforms the existing schemes.
