PERFORMANCE ANALYSIS OF 2×2 MIMO-OFDM SYSTEM USING AWGN CHANNEL WITH ALAMOUTI SPACE-TIME CODING

Abstract

Today, it may seem like Internet access is ubiquitous, but a new wireless broadband System called WiMAX (Worldwide Interoperability for Microwave Access) promises to revolutionize the utility and accessibility of the Internet. WiMAX technology has a longer range, higher spectral efficiency, and ability to connect multiple users at the same time. The range of services it can offer include voice, video, and data, as well as mobility. In this paper we are analysis the Alamouti Space-Time Coding technologies like 2×2 MIMO system under combination of digital modulation technologies like BPSK, QPSK, 8-QAM and 16-QAM with mobile communication channel AWGN used and the results shows under the Bit Error Rate versus Signal to Noise Ratio.
