FDTD Analysis of Signal and Interference Characteristics in Multi-channel Propagation over Forests for WiMAX Communication
WiMAX wireless communication has been rapidly developed for broadband mobile communication.To design excellent high performance mobile communication systems,accurate evaluation of communication systems is indispensable.Mobile WiMAX wireless communication system uses microwave carrier of 2.5 GHz band and modulation of OFDM mainly.In this paper,propagation characteristics and received electric field distribution of WiMAX wireless data communication system with high bit rate more than 10 Mbps in artificial structures such as buildings,bridge and natural environment such as forest are studied by FDTD simulation.Electric field distributions are studied by changing parameters for material constants size and position of artificial and natural structures.Propagation,reflection,scattering,interference and delay of digital code signal and error bit in received code signals are evaluated to show the environmental characteristics.
