Outage performance analysis of MIMO cognitive radio network users in fading environment

This paper investigates the performance of Multiple Input Multiple Output (MIMO) cognitive radio network to provide highly reliable communication for all users in a network and efficient utilization of radio spectrum in a fair-minded way based on outage probability. The outage probability depends on the interference from license user (i.e., primary users) in a spectrum. We develop a simulation of outage probability with respect to interference threshold and average number of primary users to evaluate performance of a cognitive radio (CR) user in faded environment.
