FDTD Analysis of Microwave Propagation and Scattering Characteristics over Forests for WiMAX Wireless Communications

摘要：

WiMAX wireless communication has been rapidly developed for broadband mobile communication including image transmission. To design excellent high performance mobile communication systems of very high speed transmission, accurate environment evaluation of com-munication systems is indispensable. In the past, building and street effects on high speed signal propagation have been studied by FDTD method. However, wave propagation and scattering characteristics by presence of forest and trees have not been so much studied. Using several material consants and structure, the effects of multiple scattering and attenuation of microwaves over forests in WiMAX wireless communications are analyzed numerically using FDTD method. These results may yield important factors for the optimum design of high performance and reliable WiMAX communication systems.
