As part of a larger scope work that studies network-based positioning, that employs timing measures, this article proposes a methodology to add Cramer-Rao Bounds (CRBs) information to the propagation model. Moreover, it enables a very quick computation of CRBs for timing, avoiding the growing computational effort resulting from Fisher's matrix formulation and its inversion for each required position...
This paper presents the development of capacitance measurement with RF signal (RFCV) for MOSFET. Such technic is fundamental to measure and extract capacitances from nanometric range oxide thickness, which are very leaky in low frequency range measurements. This method uses the control and synchronization of a vector network analyzer (VNA) with a Source Measure Unit (SMU) from a parameter analyzer...
This paper studies the potential impact of using space-time information in the mitigation of the Non-Line-Of-Sight condition in mobile subscriber's positioning systems. First of all, this work discusses the positioning problem based on measures of Time Differences Of Arrival departing from a more exact characterization of the signal statistics and including some geometrical restrictions to achieve...
