We present a set of watermarking techniques for effective covert communication over an audio signal carrier. Watermark robustness is enabled using: (i) redundant spread-spectrum fo...
In this paper, cross-layer optimization approach is applied from video coding to the physical layer through Media Access Control (MAC) layer. We mainly focus on resource allocatio...
— The multiuser multiple-input multiple-output (MIMO) broadcast channel uses multiple antennas at the transmitter to simultaneously deliver information to multiple users. Despite...
Abstract-- Wideband communications are asymptotically impossible with signals that are spread over a very wide band and are transmitted over a multipath channel unknown ahead of ti...
The scale of smart living spaces can be varied from small, e.g. a household, to large, e.g. a building or a campus, scales. As the scale of the space increases, we can expect that...
