无线视频传输系统中UWB信号绕射特性研究
Study on diffraction propagation characteristic of UWB signal in wireless video transmission system
摘要
Abstract
Since the environment of non⁃line⁃of⁃sight(NLOS)propagation is often encountered in ultra⁃wideband(UWB) wireless video transmission system,the diffraction propagation characteristic of UWB signal should be studied in this environ⁃ment. The advantage of diffraction propagation characteristic is analyzed with the time domain uniformity theory of diffraction (UTD)and physical optics(PO),and a hybrid method is presented to analyze the diffraction propagation characteristic of UWB signal in wireless video transmission system. The hybrid method utilizes a group simple recursion relation instead of the higher⁃order diffraction item in the consistency diffraction theory. This hybrid analysis method based on time⁃domain UTD⁃PO can ana⁃lyze the multi⁃diffraction propagation characteristic of UWB signal in wireless video transmission environment accurately,and im⁃prove the computational efficiency obviously.关键词
