An Ultra-wideband (UWB) employs very narrow pulses, of the order of a few nano-seconds, in order to provide high data rate communications .These narrow pulses spread the energy over a wide frequency band, and hence the name ultra-wideband (also called Impulse radio). In this paper, we will discuss the basic techniques of UWB pulse modulation and transmission design considerations using Time Hopping and Direct Sequence multiple assess modulation techniques using MATLAB Simulations .
