FuTURE B3G TDD is designed to provide 100 Mbps peak data rate in both uplink and downlink. In this paper, the MIMO channel measurement campaign carried out in BUPT campus is briefly introduced. Based on the results from the field channel measurement, the radio transmission parameters of physical layer is optimized, and the downlink performance of FuTURE B3G TDD is evaluated in system level with soft...
FuTUKE B3G TDD is designed to provide 100 Mbps peak data rate in both uplink and downlink. In this paper, based on the results from the field channel measurement, the radio transmission parameters of physical layer is optimized, and the downlink performance of FuTURE B3G TDD is evaluated in system level. To provide a multi-cell coverage, a soft frequency reuse is adopt. Further, a joint spatial and...
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 3G long term evolution (LTE) is launched by 3GPP recently, many multiple access (MA) schemes have been proposed for 3G LTE, such as multi-carrier (MC) - WCDMA, MC-time duplex-synchronized CDMA (MC-TD-SCDMA), orthogonal frequency division multiple access (OFDMA), Single Carrier Frequency Division Multiple Access (SC-FDMA), which includes IFDMA (interleaved FDMA) and DFT-S OFDM (DFT-spreading...
CSI can be utilized at the transmitter to implement close loop multiuser MIMO and obtain both full spatial multiplexing and multiuser diversity gain in uplink. In this paper, multiuser per antenna rate control (MU-PARQ) and multiuser singular value decomposition (MU-SVD) for spatial division multiplexing (SDM) of MIMO OFDM are investigated and a novel joint spatial frequency proportional fairness...
In a MIMO OFDMA multiuser system, the multiuser diversity gain can be achieved both in spatial and frequency domain by joint spatial and frequency scheduling. Although the channel estimation error (CEE) may degrade such multiuser diversity gain, little work has been performed on it. In this paper, we investigate the effect of the CEE on MIMO OFDMA downlink based on multiuser zero force beamforming...
