Spectrum Sharing Between Cellular and Mobile Ad Hoc Networks: Transmission-Capacity Trade-Off (2008)
Huang, Kaibin, Lau, Vincent K. N., Chen, Yan
Spectrum sharing between wireless networks improves the efficiency of spectrum usage, and thereby alleviates spectrum scarcity due to growing demands for wireless broadband access. To improve the...
Spatial Interference Cancellation for Multi-Antenna Mobile Ad Hoc Networks (2008)
Huang, Kaibin, Andrews, Jeffrey G., Heath, Robert W., Guo, Dongning, Berry, Randall A.
Interference between nodes is a critical impairment in mobile ad hoc networks(MANETs). This paper studies the role of multiple antennas in mitigating this interference. Specifically, a network is...
Overlaid Cellular and Mobile Ad Hoc Networks (2008)
Huang, Kaibin, Chen, Yan, Chen, Bin, Yang, Xia, Lau, Vincent K. N.
In cellular systems using frequency division duplex, growing Internet services cause unbalance of uplink and downlink traffic, resulting in poor uplink spectrum utilization. Addressing this issue,...
Spatial Interference Cancelation for Mobile Ad Hoc Networks: Perfect CSI (2008)
Huang, Kaibin, Andrews, Jeffrey G., Heath, Robert W., Guo, Dongning, Berry, Randall A.
Interference between nodes directly limits the capacity of mobile ad hoc networks. This paper focuses on spatial interference cancelation with perfect channel state information (CSI), and analyzes...
Uplink SDMA with Limited Feedback: Throughput Scaling (2008)
Kaibin Huang, Robert W. Heath, Jeffrey G. Andrews
Combined space division multiple access (SDMA) and scheduling exploit both spatial multiplexing and multiuser diversity, increasing throughput significantly. Both SDMA and scheduling require feedback...
Space Division Multiple Access with a Sum Feedback Rate Constraint (2006)
Huang, Kaibin, Heath, Robert W., Andrews, Jeffrey G.
On a multi-antenna broadcast channel, simultaneous transmission to multiple users by joint beamforming and scheduling is capable of achieving high throughput, which grows double logarithmically with...
Performance of Orthogonal Beamforming for SDMA with Limited Feedback (2006)
Huang, Kaibin, Andrews, Jeffrey G., Heath Jr, Robert W.
On the multi-antenna broadcast channel, the spatial degrees of freedom support simultaneous transmission to multiple users. The optimal multiuser transmission, known as dirty paper coding, is not...
Limited Feedback Beamforming Over Temporally-Correlated Channels (2006)
Huang, Kaibin, Heath Jr, Robert W., Andrews, Jeffrey G.
Feedback of quantized channel state information (CSI), called limited feedback, enables transmit beamforming in multiple-input-multiple-output (MIMO) wireless systems with a small amount of overhead....
