SNR Performance Verification of Different UWB Receiver Architectures

One of the most important issues in Ultra-Wideband (UWB) communication is the achievable transmission distance. Due to the regulatory issues the transmit power is strictly limited, therefore larger ranges can be achieved by using the receivers with best noise handling properties. In this paper several UWB transceiver architectures, most commonly encountered in the literature, are selected and compared with each other. From this group, three receiver structures are chosen for a simulation- and measurement-based performance verification in terms of the Signal-to-Noise Ratio in the processed signal. The firm base for the comparison among the architectures is assured by the common hardware. The implemented generic UWB transceiver enables the realization of different receiver structures by introducing only minor modifications.
