In some emerging wireless applications, such as wearable communication and low-power
sensor network applications, wireless devices or nodes not only require simple physical …

Cognitive radio (CR) is an advanced technique used for the utilization of radio spectrum. A
CR node uses the radio spectrum of a licensed user (called as primary user, PU) deviously …

In limited space scenarios, the antennas in a multiantenna cognitive radio (CR) system are
closely spaced and often experience correlation among them. In this paper, the sensing …

Due to poor (limited) scattering, a correlation among channels is inevitable, resulting in
performance degradation of wireless communication systems. In this paper, we propose a …

In this work, energy detection‐based spectrum sensing for multiple antenna receiver under
the effect of mobility is investigated by considering L number of correlated antenna …

In Cognitive Radio (CR), accurately detecting Primary User (PU) signal through spectrum
sensing techniques is the foremost requirement. For Energy Detection method, selection of …

Most of the conventional spectrum sensing algorithms are based on cognition of transmitting
signal features. The general approach for utilizing this cognition property is by bearing some …

Maximal ratio combiner output distributions of multivariate equal-correlated Nakagami-m
fading in their single-integral form are derived in this paper. The new distributions provide …

This letter investigates the performance of energy detector with multiple antennas in
cognitive vehicular networks, where the sensing signals of the secondary user are …

In limited space scenarios, the antennas in the multi-antenna cognitive radio (CR) system
