Abstract
Due to the ultrawide band property of an UWB pulse, it is difficult to digitally implement a TR-UWB system in time domain. In order to overcome this problem, we propose two types of TR-UWB systems which can be implemented in frequency-domain. One of thorn is derived from the Parseval's theorem, which results in its system performance equitable to that of time-domain based system. In addition, we propose another receiver structure which can improve the performance by exploiting the complex nature of the frequency components. Finally, through simulations, we compare the performances of two receiver structures with the time domain counterpart.
