摘要
该文提出了一种多用户MIMO系统中预矩阵及其匹配接收矩阵的鲁棒性优化算法。针对信道估计误差构造均方误差代价函数,在发射功率受限的约束条件下联合设计发射和接收矩阵,推导出了采用线性多用户MMSE接收时的最优收发机迭代算法。仿真表明,系统具有良好的鲁棒性。
A robust transceiver optimization algorithm for multi-user MIMO system is proposed. We construct system-level mean square error cost function based on imperfect channel state inforrnation（CSl）, jointly design the structure of transmitter and receivers under transmit power constraints, then a optimized algorithm for linear precoded MMSE system is proposed. Simulation results show that our algorithm is efficient to combat CSI errors.
