基于QoS的多小区下行TDD大规模MIMO系统顽健波束成形
Robust beamforming for multicell downlink TDD massive MIMO system based on QoS
摘要
Abstract
In view of multicell downlink time division multiplexing (TDD) massive multiple-input multiple-output (MIMO) systems which had imperfect channel state information (CSI), the beamforming problem that minimized the total transmit power and signal leakage power based on quality of service (QoS) was studied. First, the objective problem was approximated as a st and ard convex optimization problem. Then, by using the duality of uplink and downlink, an inner and outer layer iterative algorithm was proposed. Numerical results show that, comparing with other typical downlink multicell massive MIMO beamforming algorithms, the proposed algorithm has obvious advantages in terms of complexity and energy efficiency.关键词
