Performance analysis for multi-hop cognitive radio networks over cascaded Rayleigh fading channels with imperfect channel state information

Abstract

In this letter, we consider a cognitive radio network with imperfect channel state information where secondary users transmit signals using multi-hop relaying. When the channels between secondary users are modeled as cascaded Rayleigh fading, we derive the exact outage probability of the secondary network in an analytic form and the approximate outage probability in a closed form. Then we propose a secondary user selection scheme to minimize the outage probability. The validity of our analysis is verified through simulation.
