Abstract:

A novel framework of multiple antenna systems, which combines smart antennas(SA)with multiple-input multiple-output(MIMO)at the receiver, is proposed. The uplink SA-MIMO system is investigated. The joint optimization problem corresponding to the uplink capacity of the single-user SA-MIMO system is deduced. Then the closed-form expression of the capacity is obtained in the case of equal power allocation and the same direction-of-arrivals(DOAs)from different transmit antennas at the same antenna array, and an upper bound of the capacity is also given in the case of different DOAs at the same antenna array. After that, for the general case, a suboptimal method for the capacity optimization problem is presented. Some numerical results are also given to compare the capacities of conventional MIMO and SA-MIMO systems and show that the proposed method is viable.

提出了一种新的多天线系统架构, 该系统架构在接收端结合了智能天线技术和多输入多输出技术.对上行智能天线-多输入多输出系统进行了研究, 提出关于单用户智能天线-多输入多输出系统上行容量的联合优化问题.对于等功率分配情形, 当同一天线阵列的来自不同发送天线的到达角相同时, 得到了上行容量的闭式解, 当同一天线阵列的来自不同发送天线的到达角不同时, 得到了上行容量的上限.接着, 对于一般情形, 提出了一种求解容量优化问题的次优解方法.最后, 通过数值仿真比较了传统多输入多输出系统容量和智能天线-多输入多输出系统容量, 仿真结果表明所提出的次优解方法是可行的.
