Optimal spectrum access for a rechargeable cognitive radio user based on energy buffer state
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
On spectrum sharing between energy harvesting cognitive radio users and primary users
(
Institute of Electrical and Electronics Engineers Inc.
, 2015 , Conference Paper)
This paper investigates the maximum throughput for a rechargeable secondary user (SU) sharing the spectrum with a primary user (PU) plugged to a reliable power supply. The SU maintains a finite energy queue and harvests ...
Average ber of multihop communication systems over fading channels
(
IEEE
, 2003 , Conference Paper)
Multihop transmission is a way to attain broader coverage by splitting the communication link from the source to the destination into several, possibly shorter links/hops. This paper presents an expression for the moment ...
Performance analysis of best relay selection scheme for fixed gain cooperative networks in non-identical Nakagami-m channels
(
IEEE
, 2010 , Conference Paper)
Selecting the best relay among all the relays ready to cooperate saves system resources and utilizes the available bandwidth more efficiently compared to the regular all-relay cooperation. This scheme also achieves the ...
On physical layer security of correlated multiantenna cognitive radio receivers
(
Institute of Electrical and Electronics Engineers Inc.
, 2021 , Conference Paper)
In limited space scenarios, the antennas in the multiantenna cognitive radio (CR) system are closely spaced and often experience correlation among them. In this work, the secrecy performance of correlated multiantenna CR ...
Atmospheric turbulence effect on hybrid FSO/RF systems
(
IEEE Computer Society
, 2017 , Conference Paper)
This article is focused on the atmospheric turbulence attenuation and their effect on the hybrid free space optical and radio frequency (FSO/RF) under Qatar harsh and dry climate. Analysis has been done by calculating the ...
