چکیده
At present, telecommunication industries are highly concerned with the wireless transmission of data which can use various transmission modes, from pointto-multipoint links. It contains full mobile internet access. Various applications have already been applied so far using WiMAX, as alternative to 3G mobile systems in developing countries. The paper built a simulation model based on 802.16 OFDMPHY baseband and demonstrated in different simulation scenarios with different modulation techniques; BPSK, QPSK, 16-QAM and 64-QAM to find out the best performance of physical layer for WiMAX Mobile. The Stanford University Interim (SUI) channel model under varying parameters is selected for the wireless channel in the simulation. The performance is recorded on the basis of BER, and SNR output through MATLAB Simulation.

Using WPT as a New Method Instead of FFT for Improving the Performance of OFDM Modulation
Orthogonal frequency division multiplexing (OFDM) is used in order to provide immunity against very hostile multipath channels in many modern communication systems.. The OFDM technique divides the total available frequency bandwidth into several narrow bands. In conventional OFDM, FFT algorithm is used to provide orthogonal subcarriers. Intersymbol interference (ISI) and intercarrier interferen...
