| 摘 要： | 针对多入多出（MIMO）中继系统中接收端服务质量（QoS）的要求,即目的节点各子信道所要求达到的信噪比值（SNR）,在文中我们研究了一种中继节点和目的节点的联合预编码算法.该算法基于权值最小均方误差（WMMSE）准则,通过接收端的QoS要求选取适当的权值,从而设计出最优的预编码矩阵和检测矩阵.

| Abstract: | Focusing on the quality of service（ QoS ） requirement on each data stream at destination（in this paper we show how to achieve any set of SNRS across the subchannels） in the MIMO relay system, in this paper we present a joint precoder design at both relay and destination. The design uses a weighted minimum mean-squared error（MMSE） criterion. Furthermore, we choise the suitable weight matrix according to the QoS requirement, so that the optimum linear precoder and decoder can be derived. |
