Rex: A randomized EXclusive region based scheduling scheme for mmWave WPANs with directional antenna
Millimeter-wave (mmWave) transmissions are promising technologies for high data rate (multi-Gbps) Wireless Personal Area Networks (WPANs). In this paper, we first introduce the con...

Explicit Space-Time Codes Achieving The Diversity-Multiplexing Gain Tradeoff
A recent result of Zheng and Tse states that over a quasi-static channel, there exists a fundamental tradeoff, referred to as the diversity-multiplexing gain (D-MG) tradeoff, betwe...

On the Sum-Rate of Opportunistic Beamforming Schemes with Multiple Antennas at the Receiver
Abstract— The capacity region of Gaussian Multi-InputMultiple-Output (MIMO) broadcast channels has been shown to be achieved by dirty paper coding (DPC). However, due to the high...

A New Hybrid Space-Time Block Codes and Spatial Multiplexing Scheme with Precoding
— We present a new hybrid scheme which combines space-time block codes (STBC) and spatial multiplexing (SM) to achieve both diversity and spatial multiplexing gain. We design a n...
