多用户分布式MIMO系统的低复杂度天线选择算法
Fast antenna selection in multi-user distributed MIMO systems
摘要
Abstract
The number of antennas at the base station side in a multi-user distributed MIMO system is much larger than that of a centralized one. Accordingly, antenna selection at the base station side becomes one of the key technologies in such a system. However, traditional algorithms are too complex to be realized. A low complexity receive antenna selection algorithm based on parameter optimization is proposed to deal with the complexity problem in the uplink of multi-user distributed MIMO systems. In order to reduce the complexity, an elimination method with capacity computation replaced by iterative parameter optimization computation is introduced in the algorithm. Both complexity analysis and simulation results show that the computation complexity is largely reduced while the capacity performance is still close to that of the optimal algorithm.关键词
