BER analysis of MIMO-Wimax system using orthogonal space time block codes

The main aim of this paper is to analyze the achievement of BER in MIMO-WiMAX system using STBC and OSTBC. With increase the demand of high data rates in recent mobile radio technology We are using MIMO WiMAX system for long distance data transmission and increases system performance as well as data rate. This MIMO-WIMAX process can be simulated by using MATLAB. This achievement can be accomplished by using Alamouti, MRC and orthogonal-Space Time Block Code(OSTBC) for different modulation schemes(QPSK, BPSK, PSK, 16-QAM) under different channel circumstances like AWGN and Rayleigh for various diversity schemes alike Alamouti(2×1), MRC(1×2), OSTBC (2×2) and OSTBC(4×1).
