Multi-Array 5G V2V Relative Positioning: Performance Bounds
, 2019 We study the performance bounds of vehicle-to-vehicle (V2V) relative positioning for vehicles with multiple antenna arrays. The Cram\'{e}r-Rao bound for the estimation of the relative position and the orientation of the Tx vehicle is derived, when angle ...

Application of the Compress Sensing Theory for Improvement of the TOF Resolution in a Novel J-PET Instrument [PDF]
, 2015 Nowadays, in Positron Emission Tomography (PET) systems, a Time of Flight information is used to improve the image reconstruction process. In Time of Flight PET (TOF-PET), fast detectors are able to measure the difference in the arrival time of the two ...

Difference in Pulse Arrival Time at Forehead and at Finger as a Surrogate of Pulse Transit Time [PDF]
2016 Computing in Cardiology Conference (CinC), 2016 Pulse transit time (PTT) difference (PTTD) to the forehead and finger dynamics are compared to pulse arrival time towards the finger (PATF) dynamics during a tilt table test. Two frequency bands, where different physiological information is expected, are analyzed: low frequency (LF) influenced by both sympathetic and parasympathetic activity, and high ...

Method and apparatus for calibrating the ionosphere and application to surveillance of geophysical events [PDF]
, 1984 The columnar electron content of the ionosphere between a spacecraft and a receiver is measured in realtime by cross correlating two coherently modulated signals transmitted at different frequencies (L1,L2) from the spacecraft to the receiver using a ...
