This paper investigates several modulation techniques for IEEE 802.16 (WiMAX) based OFDM system including BPSK, QPSK, 8PSK and various levels of QAMs. The system performance is gained by dynamically choosing the modulation technique based on the channel conditions. The performance of OFDM system is accessed by using computer simulations performed using MATLAB 7.3. In this paper, transmitter and receiver models are simulated according to the parameters established by the standard, to evaluate the performance. Also, convolution coding is used to improve the system performance.
