Digital on-channel repeater (DOCR) is regarded as a desirable solution to effectively build a wide-area network of mobile terrestrial-digital multimedia broadcasting (T-DMB) services. On the other hand, the DOCR mainly suffers from interference effects caused by a strong feedback signal and a time-varying channel dispersion. In this paper, we propose a novel DOCR for use in the T-DMB system in order...
We introduce a technique to achieve dirty paper coding (DPC) capacity asymptotically with minimum feedback required reported to date in literature. Our approach called opportunistic interference management, is based on a new multiuser diversity scheme designed for wireless cellular networks. When there are K antennas at the base station with M mobile users in the cell, the proposed technique only...
Interference between nodes directly limits the capacity of mobile ad hoc networks. This paper focuses on spatial interference cancellation with perfect channel state information (CSI), and analyzes the corresponding network capacity. Specifically, by using multiple antennas, zero-forcing beamforming is applied at each receiver for canceling the strongest interferers. Given spatial interference cancellation,...
