WiMAX (Worldwide interoperability for Microwave Access) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. In this work, with the performance investigation of the WIMAX system under different applications generating high load data traffic, various modulation schemes like GMSK, BPSK, DPSK, QAM 64, etc. were introduced. The performance of WIMAX physical layer is analyzed based on the simulation results of Bit-Error Rate (BER) and Signal-to-Noise Ratio (SNR) and the results are represented in the form of tables and graphs.
