On the performance of subcarrier allocation techniques for multiuser OFDM cognitive networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers Inc., 2014)
Reconfigurable antennas (RA) have been viewed as a hardware-efficient alternative solution to multiple-input multiple-output systems whereby network users can vary the antenna radiation patterns using a single antenna ...
Clipping noise mitigation using partial transmit sequence for optical OFDM systems
(Institute of Electrical and Electronics Engineers Inc., 2014)
Orthogonal frequency division multiplexing (OFDM) is a promising technology to achieve higher data rates in optical wireless communication (OWC) systems. Unlike single carrier techniques, OFDM can easily handle inter-symbol ...

Secure communication in frequency selective channels with fade-avoiding subchannel usage
(IEEE Computer Society, 2014)
The random nature of fading channels is an enabling factor for achieving secrecy against eavesdropping. By considering the channel frequency selectivity, we propose an adaptive transmission scheme in which the faded ...
Game theoretical partially overlapping filtered multi-tones in cognitive heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2014)
Partially overlapping tones have recently been paid attention to by the researchers in cognitive heterogeneous networks (HetNets). In this paper, we introduce partial overlapping in the filtered multi-tones instead of full ...
Partially overlapping tones for uncoordinated networks
(Institute of Electrical and Electronics Engineers, 2014)
In an uncoordinated network, the link-level performance of a wireless receiver might degrade significantly due to the interference from other transmitters that share the same spectrum. As a solution, in this study, the ...
A two-antenna single RF front-end DOA estimation system for wireless communications signals
(Institute of Electrical and Electronics Engineers, 2014)
Both adaptive beamforming methods and interference management systems improve the capacity of wireless communications systems, however they may require direction of arrival (DOA) information of signals. On the other hand, ...
