The capability of Multiple Input Multiple Output (MIMO) to deliver service simultaneously to more than one user is an exceptional characteristic for the cognitive radio (CR) communication. In this paper, statistical optimization techniques are applied to assess the performance of the Quality of Experience (QoE) in CR systems, where each user has different demands. The Multiuser scenario is considered where the transmitter runs the Multibeam Opportunistic Beamforming technique to service more than one user. Closed form expressions are derived for different scenarios and obtained for four QoE indicators in the system. The performance of primary and secondary users in such scenarios are mathematically formulated and the results are compared with computer simulations.
