Ultra-Wideband (UWB) technology is a wireless transmission scheme having a bandwidth of more than 25% of a center frequency, or more than 1.5GHz. It uses very narrow band pulses of nano-seconds duration to provide very high data rate communications. The pulses in the UWB spread the energy of the signal over a large frequency range and it is extremely important to meet the requirements of ultra wideband emission mask requirements to get improved performance in the multipath environment. This paper focuses on improvement in the performance of ultra wideband multiple access modulation scheme system using improved optimal Gaussian derivative pulse shapes in the UWB multipath channel.
