摘要：
Multiple Input Multiple Output (MIMO) adds a new dimension, the spatial one, to be optimized in Cognitive Radio (CR) by delivering service simultaneously to more than one user. In this paper, statistical optimization techniques are carried out to assess the Quality of Experience (QoE) performance where each type of users has different demands. The Multiuser scenario is considered where the transmitter can accomplish an Opportunistic Scheduling approach. Closed form expressions are derived for different scenarios and obtained for the QoE indicators in the system regarding the minimum guaranteed throughput and maximum allowed scheduling delay. The primary users and secondary users performance within such scenarios are mathematically formulated and compared their results to simulations.
