Abstract: Virtual simulation experiments mainly use virtual reality,human interaction,database and other technologies.By providing a high-quality teaching experiment platform,students can conduct experiments in an open,shared and interactive virtual simulation environment to solve the problems of lack of real experimental teaching resources,single content,and outdated models.A virtual simulation teaching platform is designed for the signal attenuation phenomenon of wireless communication technology.A virtual simulation teaching platform is designed for the signal attenuation phenomenon of wireless communication technology.Specially,according to the relationship between the relevant parameters of wireless communication and the decaying degree of signal attenuation,the wireless path loss prediction formula is selected as the basis for the development of this virtual simulation experiment platform.Moreover,this proposed platform enhances the interactive of virtual simulation experiment teaching,which develops students' experiment ability and innovation ability.
