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 ...
Energy-efficient cooperative relaying protocol for full-duplex cognitive radio users and delay-aware primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper considers a network in which a primary user (PU) may cooperate with a cognitive radio (CR) user for transmission of its data packets. The PU is assumed to be a buffered terminal operating in a time-slotted ...
A New Wearable ECG Monitor Evaluation and Experimental Analysis: Proof of Concept
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Conference Paper)
Electrocardiogram (ECG) is an electrical activity of the heart, which can be recorded by placing electrodes near heart or on the limbs. ECG is a vital body signal, which reflects the heart health condition. This paper ...
Efficient FPGA-based implementation of a novel dual mode spectrum sensing technique
(2013 , Conference Paper)
Cognitive radio networks require an efficient and reliable method of sensing the spectrum. In this paper, we introduce and implement a new dual mode spectrum sensing technique that is based on combining Quickest Detection ...
A novel peak search & save cyclostationary feature detection algorithm
(
Institute of Electrical and Electronics Engineers Inc.
, 2016 , Conference Paper)
Spectrum sensing is a key task in any cognitive radio network. On the other hand, a literature survey in this topic shows a lack of implementation and testbeds for spectrum sensing techniques. In this paper, we plot the ...
Multiuser scheduling on downlink communications by using adaptive hierarchical modulation
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
In this paper, we propose a novel downlink system that is able to maximize the number of users which could be served with high correct decoding probability while, minimizing the total consumed energy for data reconstruction ...
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 ...
Secure Transmission of IoT mHealth Patient Monitoring Data from Remote Areas Using DTN
(
Institute of Electrical and Electronics Engineers Inc.
, 2020 , Article)
In remote rural areas without continuous Internet connectivity, it is hard to envisage the use of mHealth applications for remote patient monitoring. In such areas, patients need to travel long distances to reach the nearest ...
Modified QR-D and MMSE PMI selection technique for MIMO closed loop spatial multiplexing in LTE/LTE-advanced
(2013 , Conference Paper)
Limited feedback closed-loop spatial multiplexing evolved as an attractive technique during the development of Multi Input Multi Output (MIMO) in Long Term Evolution (LTE). Spatial multiplexing involves transmitting ...
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 ...
