| Abstract: | This paper describes a low-complexity transceiver architecture for the 3.1-10.6 GHz Ultra-Wideband radio. The proposed system transmits passband pulses using a pulser and antenna, and the receiver front-end downconverts the signal frequency by subsampling, thus, requiring fewer circuit blocks than a traditional narrowband approach. In the digital section, analytic signal processing has been proposed to compensate for the limitations of the analog circuits. By exploring the properties of analytic signals, the system achieves a time resolution finer than the sampling period, which is useful for locationing or ranging applications. | ||
