A Study on the Performance Improvement of UWB-IR System for Intelligent High Speed Multimedia Service.

Ultra-wideband (UWB) technology has been considered to offer an innovative solution for future short-range high-speed wireless communication. Interference suppression is important for the UWB devices to operate over spectrum with established narrowband systems. But it's difficult to secure a QoS of high quality because it coexists other system that was used same band. We need a adaptable change of the system that follow the changing channel environment. In this paper, derived monocycle pulse that application is possible within permission frequency band that establish in The Federal Communications Commission(FCC). Also, PPM modulated TH IR system simulator is designed in Two-path environment. It is analyzed monocycle pulse specific property and system performance using simulator. [ABSTRACT FROM AUTHOR]
