A Performance Study of WIMAX OFDM Includes Space-Time Block Coding

Age of wireless mobile contact is approaching rapidly. Users are increasingly demanding flexible and convenient communication modes that are accessible without losing quality and efficiency. The market for high-speed broadband infrastructure with lower energy costs. The challenge is to provide high performance, high speed, and portable customers. The response to these criteria could be that Worldwide Microwave Connectivity Interoperability (WiMAX) is a high technology that provides sub-channel services to individuals and groups. The effect of Space-Time Block Coding (STBC) on WIMAX performance is studied in this paper and compare it without STBC using Model Architecture for the WiMAX Orthogonal Frequency Division Multiplexing (OFDM) Physical Layer.
