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 ...
Optimization of antenna beamwidth under blockage ımpact in millimeter-wave bands
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper, beam expansion and optimization approach is proposed as a solution to alleviate blockage impact at millimeter wave (mm-wave) frequency bands. Directional communication in mm-wave bands provides opportunities ...
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 ...
Optimization of aerial base station location in LAP for disaster situations
(Institute of Electrical and Electronics Engineers, 2015)
Aerial telecommunication platforms will be a part of the future communication networks. In this paper, we address the issue of optimizing the location of Aerial Base Stations (ABS) in Low Altitude Platforms (LAP) to minimize ...
Short paper: Secure multi-user transmission using CoMP directional modulation
(Institute of Electrical and Electronics Engineers, 2015)
Directional Modulation is a recently developed multi-antenna technique for secure transmission. It allows to transmit signals in desired directions while distorting the signal in the other directions. To secure the ...
N-continuous OFDM with CP alignment
(Institute of Electrical and Electronics Engineers, 2015)
In this paper, we propose an out-of-band (OOB) reduction method which incorporates with multipath channel and N-continuous OFDM structure. By exploiting the inevitable guard periods between OFDM symbols, i.e., cyclic prefix ...
Iterative tap pursuit for channel shortening equalizer design
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this work, an iterative tap pursuit algorithm for designing channel shortening equalizers is proposed. Similar to pursuit algorithms, a residual vector is initialized with a desired target impulse response, which is ...
