DFT-Based Multi-Directions Directional Modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2019 , Article)
In this letter, a physically secure multi-directions directional modulation scheme is proposed. The scheme provides an adaptive beam-width assignment, where each user is granted a different beam width based on its channel ...
Statistical analysis of electromagnetic field inside a jet engine using the reverberation chamber approach
(
Electromagnetics Academy
, 2012 , Article)
In this paper, the electromagnetic field distribution inside a jet engine is studied through full wave analysis. Results are statistically analyzed by comparisons to the models used for the reverberation chamber with a ...
On the Performance of Hadamard Ratio Detector-Based Spectrum Sensing for Cognitive Radios
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
We consider the problem of multiantenna spectrum sensing (SS) in cognitive radios (CRs) when the receivers are assumed to be uncalibrated across the antennas. The performance of the Hadamard Ratio Detector (HRD) is analyzed ...
On the Design of a Relay-Assisted Network
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
A relay network composed of a source, a set of relays, and a destination is considered. A queueing framework is proposed, in which each node maintains a buffer to store its incoming traffic. An optimization-based formulation ...
On orthogonal band allocation for multiuser multiband cognitive radio networks: Stability analysis
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Article)
In this work, we study the problem of band allocation of Mi buffered (i.e., with data queues capable of storing incoming traffic packets) secondary users (SUs) to Mp primary frequency bands licensed to (owned by) Mp buffered ...
On the more accurate channel model and positioning based on time-of-arrival for visible light localization
(
SPIE
, 2017 , Article)
This paper presents an improved propagation channel model for the visible light in indoor environments. We employ this model to derive an enhanced positioning algorithm using on the relation between the time-of-arrivals ...
