In this paper, a novel low-complexity time-of-arrival (TOA) estimation strategy and a conceptual receiver setup for ultrawideband (UWB) signals is proposed, and its performance is evaluated. The receiver consists of an analog peak detector followed by two filters with different time constants. From two exponentially decaying signals, the TOA of the first peak of the received signal is reconstructed...
The International Rosetta Mission was successfully launched on March 2, 2004. NASA's contribution to this mission consists of the following three hardware experiments: Alice (an ultraviolet spectrometer), the ion and electron sensor (IES - a plasma instrument), and the microwave instrument for the Rosetta orbiter (MIRO), as well as other components. Collectively these elements are known as the U.S...
