Fast neighbor positioning and medium access in wireless networks with directional antennas
(2013)We study the problem of fast neighbor positioning and medium access in wireless networks with directional antennas. In this problem, the cross-layer dimension inherently comes into stage through the impact of PHY-layer ... -
Multi-Metric Waveform Optimization for Multiple-Input Single-Output Joint Communication and Radar Sensing
(2022)Joint communication and radar sensing (JCAS) integrates the two functions into one system, sharing one transmitted signal. In this paper, we investigate JCAS waveform optimization in communication-centric systems, where a ... -
On the use of distributed directive antenna arrays in mobile OFDMA networks
(2011)Distributed Omni Antenna Systems (OASs) have been proposed to increase the capacity of Broadband Wireless Access (BWA) systems. We investigate the extension of such systems by employing distributed Directive Antenna Arrays ... -
Pseudopotentials: A Simplified Model for Certain Types of Array Elements
(2009)The results obtained by modeling an infinite linear array of electrically short dipoles by an array of pseudopotentials (the pseudopotential is a quantum-mechanical analog of the dipole) can be used for the analysis of ... -
Spatial multiplexing based on distributed antenna arrays for mobile WiMAX networks
(2010)A novel cell architecture based on Distributed Antenna Arrays for next generation mobile WiMAX systems is proposed. By exploiting Spatial Multiplexing and beamforming techniques, our target is to maximize the throughput ...
