Research on UWB for High Speed Wireless Transmission in Indoor Environment

In this paper, UWB technology for high speed wireless transmission in indoor environment is introduced, and then the performance is analyzed and compared when it is applied to high-speed wireless transmission in indoor environments, including shape of impulse, modulation methods, multi-access technology, characterization of UWB channel in indoor environments, and structure of UWB communication system for time-hoping pulse position modulation(TH-PPM) method. at last, it concludes that the performance is good and realization is easy for UWB with pulse position modulation, gauss waveform and TH technology.
