Opportunistic Grassmannian Beamforming for Multiuser and Multiantenna Downlink Communications
Scheduling in a broadcast channel based on partial channel-state-information at the transmitter is carried out in an opportunistic way. In this paper, the number of generated beams...

Modulation Schemes Based on Orthogonal Pulses for Time Hopping Ultra Wideband Radio Systems
— This paper describes a combined modulation scheme for time hopping ultra wideband (TH-UWB) radio systems using on-off keying (OOK) and pulse shape modulation (PSM). For this sc...
