Evaluation of Mobile WiMAX System Performance

Mobile WiMAX as an OFDMA (Orthogonal Frequency Division Multiple Access) mobile broadband air interface is a solution to the requirements for mobile internet services. It has been accepted by ITU as 3G standard last year. The work presented in this paper focuses on evaluation of the Mobile WiMAX system performance in which Full-Queue and VoIP traffic are considered both in downlink and uplink We have proposed a virtual MIMO scheduling process in uplink We also discussed the system throughput of three frequency reuse schemes including reuse 1, reuse 3 and the FFR (Fractional Frequency Reuse). The former work is concentrated on the spectrum efficiency in [3-6], while this paper is a valuable replenishment to them.
