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 ...
A comparative review on the wireless implantable medical devices privacy and security
(Institute of Electrical and Electronics Engineers, 2014)
Nowadays wireless communication is playing a vital role in implantable medical devices (IMDs) on health-care applications. It has many advantages in remote health monitoring, treatment and prediction for critical cases. ...
Numerical characterization of in vivo wireless communication channels
(Institute of Electrical and Electronics Engineers Inc., 2014)
In this paper, we numerically investigated the in vivo wireless communication channel for human male torso at 915 MHz. Results show that in vivo channel is different than the classical communication channel and location ...
Mobility performance of macrocell-assisted small cells in Manhattan model
(Institute of Electrical and Electronics Engineers Inc., 2014)
Macrocell-assisted small cell concepts, such as "Phantom cell concept" and "soft cell concept", have been proposed previously for interference management, flexible cell planning, and energy saving in dense small cell ...
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 ...
Cyclic feature concealing cp selection for physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2014)
Cyclic prefix (CP) utilizing techniques such as orthogonal frequency division multiplexing (OFDM) and singlecarrier frequency domain equalization (SC-FDE) offer significant advantages in equalizing the effect of time ...
