In this paper, the outage performance of a cognitive radio network with a pair of secondary
transmitter and receiver is investigated in the presence multiple primary users over a …

Nowadays there is an increasing demand to provide a real-time environmental information.
So, the growing number of mobile devices carried by users establishes a new and fast …

In this paper, we analyse the performance of infrastructure-based fixed relay with multi-
antenna in cognitive radio. We derive the mathematical expression for detection probability …

The increasing demand of wireless applications has increased need for Radio Frequency
(RF) spectrum. But the fixed spectrum allocation policy has created a spectrum scarcity …

In this paper, the performance of a multiple antenna-based cooperative spectrum sensing in
Cognitive Radio (CR) is discussed. The system model consists of a single Primary User (PU) …
