Random Aerial Beamforming for Underlay Cognitive Radio with Exposed Secondary Users
(IEEE Vehicular Technology Society, 2016)
In this paper, we introduce the exposed secondary users problem in underlay cognitive radio systems, where both the secondary-to-primary and primary-to-secondary channels have a Line-of-Sight (LoS) component. Based on a ...
On Efficient Channel Modeling for Video Transmission over Cognitive Radio Networks
(Springer, 2016)
This paper investigates the problem of video transmission over cognitive radio networks with the objective of maintaining continuous video playback while gracefully degrading the quality of the reconstructed video sequences, ...
A Unified Approach for Probability of Detection Evaluation over Generalised Fading Channels
(Institution of Engineering and Technology, 2016)
In this paper, we revisit energy detection-based spectrum sensing cognitive radio systems operating over generalised fading channels. In particular, we derive closed-form exact expressions as well as lowand high-signal-to-noise ...
Capacity of Fox's H-function Fading Channel with Adaptive Transmission
(Institution of Engineering and Technology, 2016)
Novel closed-form exact expressions for the capacity of the recently-introduced Fox's H-function fading channel are derived. The expressions are obtained assuming different types of adaptive transmission strategies, namely, ...
Spectrum Sensing Via Reconfigurable Antennas: Fundamental Limits and Potential Gains
(Springer, 2016-07)
We propose a novel spectrum sensing technique in cognitive radio networks that provides diversity and capacity benefits using a single antenna at the Secondary User (SU) receiver. The proposed scheme is based on a ...
Closed-form Exact and Asymptotic Expressions for the Symbol Error Rate and Channel Capacity of the H-function Fading Channel
(IEEE Vehicular Technology Society, 2016-04)
In this paper, we derive closed-form exact and asymptotic expressions for the symbol error rate (SER) as well as channel capacity when communicating over the Fox's H-function fading channel. The SER expressions are obtained ...
