The Worldwide Interoperability for Microwave Access (WIMAX) is the new era of communication and is the latest technology. It is approved by IEEE 802.16 group, which is a standard for point to the multi-point wireless networking. This paper investigates the performance of WiMAX physical layer based on the IEEE 802.16e standard under the different combinations of digital modulation schemes. The effect of varying coding rate and cyclic prefix are also the investigated in this paper.
