PERFORMANCEANALYSIS OF2X2MIMOand1X2SIMO SYSTEMS USING DIFFERENT MODULATION TECHNIQUE WITH RAYLEIGHCHANNEL

Abstract

WiMAX which represents (Worldwide Interoperability for Microwave Access) is a major part of broad band wireless network having IEEE 802.16 standard provides innovative fixed as well as mobile platform for broad-band internet access anywhere in anytime. IEEE 802.16 standard has bandwidth of 2GHz-11GHz for fixed applications and 2-6GHz for mobile applications. It is considered the most interesting opportunity which is able to provide data throughput up to 70 Mbps and radio coverage distances of almost 50 kilometers, and to complete wired network architectures, ensuring a cheap flexible solution for the last-mile. WiMAX can be seen as the fourth generation (4G) of mobile communications systems. Pursuance for better ways of living has been instrumental in advancing human civilization. In this project analysis of the multiple antenna technologies like Single input signal output antenna system, multiple input multiple output antenna system under different combination of modulation technologies (BPSK, QPSK, 8-QAM and 16-QAM) with Additive white Gaussian noise channel used and the performance results shows under the bit error rate versus signal to noise ratio.
