Abstract

In this paper the detection performance of relay based cognitive radio networks is studied. Relays are assigned in cognitive radio networks to transmit the primary user's signal to cognitive coordinator or CPU thus achieving cooperative spectrum sensing. The soft fusion rule is used at the relays which acts as amplify and forward relays. For the detection purpose the energy detector is employed at the cognitive coordinator. Sensing performance is analyzed for different fading channels and comparison between different relay conditions is also studied.
