On fair interference management in cognitive radio networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this paper, we consider power optimization problem in cognitive radio (CR) networks. The aim is to protect the licensed primary users (PUs) from unequal performance degradation by secondary users (SUs). A min-max ...
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 ...
Hybrid precoding for mm Wave massive MIMO systems with generalized triangular decomposition
(Institute of Electrical and Electronics Engineers Inc., 2018)
Hybrid precoding schemes have recently gained a great attention for millimeter wave (mmWave) massive multiple-input-multiple-output (massive MIMO) communication systems because of offered cost and low-power consumption ...
A flexible hybrid waveform
(Institute of Electrical and Electronics Engineers Inc., 2017)
Cellular systems of fifth generation (5G) require a waveform with flexible guard interval length along with a low power consumption. Different cyclic prefix (CP) durations in long term evolution (LTE) result in loss of ...
A novel indoor channel model for tvws communications based on measurements
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper, we present an indoor measurement campaign for TV white space bands inside a university building. The measurement results are compared with different indoor propagation models in the literature. We observed ...
Communications scenarisos and a new mixed numerology set for flying base stations in 5g and beyond
(Institute of Electrical and Electronics Engineers Inc., 2018)
In many ongoing universal projects, base stations are located in the different type of aerial vehicles with the increasing number of aeronautical platforms and applications. It triggers the different research opportunities ...
Enhancing the security performance of ostbc using pre-equalicodization
(Institute of Electrical and Electronics Engineers Inc., 2017)
In this study, we first quantify the secrecy performance achieved by employing precoded orthogonal space time block coding (POSTBC) in order to use it as a benchmark for comparison purposes with a new proposed security ...
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 ...
User association techniques in future heterogeneous networks
(Institute of Electrical and Electronics Engineers Inc., 2017)
The exponential increase in the demand of data rate and scarcity of the available spectrum have evolved to the more advanced network topology which efficiently utilizes the radio spectrum such as Heterogeneous Networks ...
