Abstract

This project presents the simulation of Worldwide Interoperability for Microwave Access (WiMAX) system. Previous technology such as Digital Subscriber Line (DSL) has coverage limitation. WiMAX can solve this limitation. This project only focuses on the Orthogonal Frequency-Division Multiplexing (OFDM) which is adopted by WiMAX on its physical layer. The OFDM is uses adaptive modulation technique for modulator and demodulator. The OFDM model built in this project including the transmitter and receiver. MATLAB software tool is used to build the OFDM model and analysis the performance of WiMAX system. Hence the investigation of the performance of OFDM physical layer in WiMAX system by using different adaptive modulation techniques like Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), Quadrature Amplitude Modulation is done. The performance analysis is based on the Bit Error Rate (BER), Signal to Noise Ratio (SNR) and Probability Error (Pe). The WiMAX system used 64 QAM at near the base station and followed by 16 QAM and QPSK. BPSK is used at the cell boundary. The WiMAX system has freedom to choose the modulation techniques.
