考虑了多用户多输入多输出（MIMO）蜂窝系统的加权和速率最大化问题，其中一个全双工（FD）基站（BS）同时为多个半双工（HD）上行链路（UL）和下行链路（DL）用户提供服务，同时考虑了不完善的信道知识。利用加权和速率问题与加权最小均方误差问题之间的关系，通过迭代收敛算法实现收发机矩阵的联合设计。仿真结果证实了准确的信道估计在FD系统中的重要性。
We consider a weighted sum-rate maximization problem for a multiuser multiple-input multiple-output (MIMO) cellular system where a full-duplex (FD) base-station (BS) serves multiple half-duplex (HD) uplink (UL) and downlink (DL) users simultaneously while taking the imperfect channel knowledge into consideration. By exploiting the relationship between weighted sum-rate and weighted minimum-mean-squared-error problems, joint design of transceiver matrices can be obtained through an iterative convergent algorithm. Simulation results confirmed the importance of accurate channel estimation in FD systems.
