Multiuser Zero Forcing Beamforming (MU-ZFB) can be adopted to exploit the multiuser spatial multiplexing gain and diversity gain in downlink by spatial multiuser scheduling. On the other hand, multiuser joint subcarrier allocation can obtain multiuser diversity gain in frequency domain. In this paper, a novel joint Spatial and Frequency Proportional Fairness (SFPF) scheduler is proposed to achieve...
For multiuser MIMO system, zero forcing beamforming (ZFB) can be adopted to exploit the multiuser spatial multiplexing gain and diversity gain in downlink by spatial multiuser scheduling. On the other hand, multiuser joint subcarrier allocation can obtain multiuser diversity gain in frequency domain. In this paper, a novel joint spatial and frequency proportional fairness (SFPF) scheduler is proposed...
Since the channel reciprocity can be obtained in TD-SCDMA LTE system, the channel status information (CSI) can be exploited at the transmitter to implement multiuser spatial division multiplexing (SDM) and obtain both the spatial multiplexing gain and multiuser diversity gain efficiently. In this paper, zero forcing beamforming (ZFB) and multiuser per antenna rate control with antenna selection (MU-PARC-AS)...
MIMO can enhance the performance of wireless system greatly. However, the limited battery life and terminal size of the UE in a cellular system put a constraint on the performance enhancement by MIMO. Especially when the transmitter has more antenna than the receiver in downlink, the conventional MIMO schemes can only exploit partial spatial multiplexing gain and diversity gain. For different users'...
