摘要

本文考虑了一组干扰共信道链路的功率和阵列权重的联合优化，给定了每条链路的期望容量。所有的发射机和接收机都假定有阵列天线。给出了一种确定连杆参数的迭代方法。在这种方法中，干扰链路的期望容量是控制参数。结果表明，迭代法不能使网络吞吐量最大化。减少每个链路上独立数据流的数量可以提高网络性能。

Control using capacity constraints for interfering MIMO links

This paper considers joint optimization of power and array weights for a set of interfering cochannel links, given the desired capacity for each link. All transmitters and receivers are assumed to have array antennas. An iterative method for determining the link parameters is given. In this method, the desired capacities for the interfering links are the control parameters. It is also shown that the iterative method does not maximize the network throughput. Reducing the number of independent data streams for each link may enhance the network performance.
