Summary :

WiMAX wireless communication has been rapidly developed for broadband mobile communication. Mobile WiMAX communication system uses microwave carrier of 2.5 GHz frequency band and modulation is OFDM mainly. By using OFDM technique, WiMAX provide high speed and reliable communication against multi pass interferences due to the presence of obstacles in communication channels. To design excellent high performance mobile communication systems, accurate evaluation of communication system is indispensable. By using parallel FDTD, we studied fundamental characteristics of microwave propagation and scattering in urban area. We also studied wave propagation and scattering by forest and trees using FDTD method. The effects of multiple scattering and attenuation of microwave by forest are severe factors of high speed wireless communications. In this paper, signal propagation and receiving characteristics of OFDM modulated wave are studied by parallel FDTD method. Propagation, reflection, scattering, interference and delay of digital code signals in received code signals are evaluated to show the environmental characteristics. Parallel FDTD methods are applied for signal and noise analysis about several different complex models and inhomogeneous materials such as forests in long distance communication channels.
