(English Abstract)
Ultra-wideband(UWB) communication applications is a recent innovation due to high transmission rate and low power emission. Therefore, it is important to research UWB signal's characteristics and modulation methods to apply to various UWB communication technologies. In this paper the characteristics of Gaussian monopulse which is capable of using UWB communication was analyzed and we compared the performance of PPM and PAM modulation method. Also we analyzed the interference effect of QPSK system with different center frequencies in the present of various UWB noises and simulated simple UWB transceiver system.
