Performance Analysis of Energy Detection over Mixture Gamma based Fading Channels with Diversity Reception
Omar Alhussein, Ahmed Al Hammadi, Paschalis C. Sofotasios +4
The present paper is devoted to the evaluation of energy detection based spectrum sensing over different multipath fading and shadowing conditions. This is realized by means of a u…
Energy Detection of Unknown Signals over Cascaded Fading Channels
Paschalis C. Sofotasios, Lina Mohjazi, Sami Muhaidat +2
Energy detection is a favorable mechanism in several applications relating to the identification of deterministic unknown signals such as in radar systems and cognitive radio commu…
Unified Analysis of Cooperative Spectrum Sensing over Composite and Generalized Fading Channels
Ahmed Al Hammadi, Omar Alhussein, Sami Muhaidat +3
In this paper, we investigate the performance of cooperative spectrum sensing (CSS) with multiple antenna nodes over composite and generalized fading channels. We model the probabi…
RF-Powered Cognitive Radio Networks: Technical Challenges and Limitations
Lina Mohjazi, Mehrdad Dianati, George K. Karagiannidis +2
The increasing demand for spectral and energy efficient communication networks has spurred a great interest in energy harvesting (EH) cognitive radio networks (CRNs). Such a revolu…
