Abstract

Multiple Input Multiple Output (MIMO) systems are increasingly being adopted in communication systems. This network uses multiple antenna for communication and spatial dimension method in addition to time and frequency without changing the bandwidth of the system. The system can also be accessed with the Worldwide Interoperability for Microwave Access (WIMAX) IEEE 802.16 standards. MIMO network uses wireless Metropolitan Area Network (MAN). The inclusion of MIMO in the WIMAX system is to provide a robust platform for space, time and frequency selective fading conditions. This system also increases the data rate and system performance. A Bit Error Rate (BER) analysis is presented for an image for the MIMO system with finite-bit feedback in QAM modulation technique. The transmitting signal consists of a rotational precoder, followed by Alamouti codes and Orthogonal Space-Time Block Code (OSTBC), through which the full diversity gain is achieved when a linear receiver such as Zero-Forcing (ZF) is used. The simulation of the MIMO-WIMAX model is done using MATLAB. The performance of the MIMO-WIMAX system has been carried out using different modulation schemes under channel conditions like AWGN for Alamouti and OSTBC. The execution of MIMO-WIMAX framework has been completed using Alamouti and OSTBC for various modulation techniques for different parameters like BER, Root Mean Square Error (RMSE), Peak Signal to Noise Ratio (PSNR) and modulation order.
