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 ...
Achieving secure communication through pilot manipulation
(Institute of Electrical and Electronics Engineers, 2015)
Raising concerns about the security of wireless communication led researchers develop new concepts to keep information secret from eavesdroppers. Among them, physical layer security relies on the features of the wireless ...
Suppressing alignment: An approach for out-of-band interference reduction in OFDM systems
(Institute of Electrical and Electronics Engineers, 2015)
In this work, we introduce a novel approach, called suppressing alignment, to reduce the out-of-band (OOB) interference of orthogonal frequency division multiplexing (OFDM) systems. Suppressing alignment exploits the ...
A survey: Spoofing attacks in physical layer security
(IEEE Computer Society, 2015)
Increasing demand on wireless communications also increases the issues related to communication security. Among different security solutions, physical layer security have recently been gaining many interests by the ...
Air-Ground Doppler-delay spread spectrum for dense scattering environments
(Institute of Electrical and Electronics Engineers, 2015)
Applications using Air-Ground communications are expected to grow in the future. Low altitude phases of these wireless links are considered sever channels, as they experience huge delay and Doppler spreads, however, they ...
An OFDM signal identification method for wireless communications systems
(Institute of Electrical and Electronics Engineers, 2015)
Distinction of orthogonal frequency-division multiplexing (OFDM) signals from single-carrier signals is highly important for adaptive receiver algorithms and signal identification applications. OFDM signals exhibit Gaussian ...
Joint subcarrier and antenna state selection for cognitive heterogeneous networks with reconfigurable antennas
(Institute of Electrical and Electronics Engineers, 2015)
Reconfigurable antennas (RA) offer an emerging technology that allows wireless devices to alter their antenna states determined by different radiation patterns to maximize received signal strength. In this paper, we consider ...
A windowing technique for optimal time-frequency concentration and aci rejection in ofdm-based systems
(Institute of Electrical and Electronics Engineers, 2015)
In this paper, we introduce a windowing technique, which provides optimal time-frequency containment and maximal adjacent channel interference (ACI) rejection for orthogonal frequency-division multiplexing (OFDM)-based ...
