The synthesis of pencil beam and arbitrarily shaped beam patterns of linear antenna arrays (LAA) using reduced number of antenna elements attracts the attention of researchers in recent years. In this paper, a hybrid beamforming technique based on th

In cognitive radio (CR), the sensitivity of the spectrum sensing (SS) algorithms depends mainly on several factors such as the receiver sensitivity, the antenna gain, the antenna efficiency and the SS algorithm itself. Researchers depend mainly on a

Cognitive radio (CR) is perceived as an intelligent solution to the incompetence of spectrum utilization. The efficacy of any CR system depends on the accuracy of the spectrum sensing (SS) technology used. Therefore, the SS is considered as a substan
