Abstract

We address the problem of Mean Square Error (MSE) transceiver design for point-to-multipoint transmission in multi-user Multiple-Input-Multiple-Output (MIMO) systems. We solve the problem of minimizing the downlink sum MSE under a sum power constraint by jointly optimizing the linear transmitters and receivers. Our result is based on a "duality" between downlink and uplink MSE regions. It states that downlink and uplink share the same achievable MSE region under a sum power constraint. Thus, the problem of downlink design can be solved efficiently by focusing on an equivalent uplink problem.

线性多用户MIMO系统下行链路和mse收发器优化

我们解决了多用户多输入多输出(MIMO)系统中点对多点传输的均方误差(MSE)收发器设计问题。我们通过联合优化线性发射器和接收器，解决了在和功率约束下下行链路和MSE最小的问题。我们的结果是基于下行链路和上行链路MSE区域之间的“对偶性”。在和功率约束下，下行链路和上行链路共享相同的可实现MSE区域。因此，通过关注等效上行问题，可以有效地解决下行链路设计问题。
