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 ...
A microcontroller-based wireless multichannel neural data transmission system
(Institute of Electrical and Electronics Engineers, 2017)
Chronically implantable microelectrode arrays enable multichannel electrophysiological recordings from the mammalian brains during behavioral experiments. Wireless data transmission systems combined with the microelectrode ...
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 ...
Waveform design principles for 5G and beyond
(Institute of Electrical and Electronics Engineers Inc., 2016)
Various emerging applications in future wireless networks require rethinking the access techniques not only from the capacity perspective but also satisfying a wide variety of requirements under the same framework. Traditional ...
Channel independent physical layer security
(Institute of Electrical and Electronics Engineers Inc., 2016)
Security is one of the key requirements of wireless communication systems. By exploiting the broadcast nature of wireless medium, a malicious user might attempt to mislead the legitimate nodes, intercept the communication ...
Static cyclic prefix alignment for OFDM-based waveforms
(Institute of Electrical and Electronics Engineers Inc., 2016)
The cyclic prefix (CP) alignment is an appealing technique for achieving multiple goals such as peak-to-average power ratio (PAPR) reduction, out-of-band (OOB) leakage suppression, and physical layer (PHY) security. It ...
