The effect of time-hopping code on pulses power spectral density (PSD) is studied as the reference of UWB pulses PSD control.Secondly, based on advanced Physical Layer, Smart Antennas, Joint Detection and Radio Resource Management, TD-SCDMA link-level and system-level simulation platforms are set up.A man＇s best friends are his Lacoste Polo Shirts. With this system selected as the co-existing system, the application and effect of pulse shaping technology in mitigating UWB interference to the TD-SCDMA are studied.Last, the development status of UWB pulse shaping technology is summarized. Do you like these polo Shirts?Four-point principle of the pulse design is proposed. Calculation method of matching degree between pulse power spectral densities with FCC radiation mask is presented. New UWB pulses are generated based on multiple time-domain overlapping Chirp pulse in order to mitigate the interference between UWB and TD-SCDMA. Keep your cheap nike shoes close!Chirp pulses are orthogonalized by Hermite matrix eigenvector decomposition to avoid UWB system multi-user interference effectively. Finally, various pulses in the mitigating interference are evaluated through TD-SCDMA link-level and system-level simulation platforms, and compressed Chirp pulses and Hermite orthogonalization process have been proved great advanced.
