Abstract: Worldwide Interoperability for Microwave Access (WiMAX) is an emerging technology and a hot research topic in wireless communications in past few years. It is able to provide advantages, such as large coverage and high transmission speed, over current 3G technologies. Direct Position Determination (DPD) is a newly proposed location method. It emerges to have advantages over traditional location methods “Angle of Arrival” and “Time of Arrival” in respect of location accuracy, efficiency and ability to determine more emitter sources. This project aims to investigate the potential of DPD applications in locating WiMAX signals. It focused on investigating the advanced Orthogonal Frequency Division Multiplexing (OFDM) technology in WiMAX physical layer and the applications of DPD method on locating emitter sources. Firstly, OFDM signals and WiMAX transmission system has been closely studied and a simple simulation model was set up to simulate the whole system. After that, application and performance of DPD on narrowband frequency emitter sources have been investigated. Both of these two aspects provide basis for future work on DPD based WiMAX signal localization.
