Abstract: The mobile Worldwide Interoperability for Microwave Access (WiMAX) is based on IEEE 802.16e standard used for wireless Metropolitan Area Network (MAN). The IEEE 802.16e standard supports high data rate and high capacity in mobile Broadband Wireless Access (BWA). The inclusion of Multiple Input Multiple Output (MIMO )in mobile WiMAX system provides a robust platform for space, time and frequency selective fading conditions and increases both data rate and system performance. In this paper, the MIMO-mobile WiMAX using Space Time Block Codes (STBC) technique is developed for both adaptive modulation and constant modulation schemes (BPSK,QPSK,QAM) with the consideration of 1/2, 3/4 code rate to determine and analyse Bit Error Rate (BER) performance under AWGN, Rayleigh and Rician channels. The simulation of MIMO-mobile WiMAX model is done by using MATLAB.
Keywords: BER, MIMO, STBC, WiMAX Systems.
