Abstract
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) and several Secondary Users (SU) and one fusion center (FC) is proposed to detect the activities of PU. Here, the SUs are playing the role of a relay which operates either in Amplify and Forward (AF) or in Decode and Forward (DF) mode. Each relay is having multiple receiving antennas and only one transmitting antenna. We have reached a closed-form expression of the detection probability (\( P_{d} \)) and false alarm probability (\( P_{f} \)) in presence of Rayleigh Fading channel. The impact of number of relays and number of antennas in each relay is highlighted in our model. We have validated our analytical model by MATLAB simulation.
