The thesis presents and demonstrates methods to characterize high-speed (> 10 Gbaud) signals in fiber optic communication systems and networks, including acquisition of the optical signal intensity, amplitude, phase and polarization. These quantities are necessary for the analysis of system performance, both in research and development stages, as well as for monitoring and management of operati...

background: intervertebral disc herniation has two common types, extrusion and protrusion, which may affect the adjacent vertebrae.in addition, it is associated with significant signal changes in t1 mri (short tr/te) and t2 mri (long tr/te).   methods: the present study is a cross-sectional analytic one, in which sampling was performed retrospectively. cases were randomly selected from the pati...

In this work we study the topic of high-resolution adaptive sampling of a given deterministic signal and establish a clear connection to classic analyses of high-rate quantization. More specifically, we formulate solutions to the task of optimal high-resolution sampling of one-dimensional signals, which are shown as the counterparts of well-known results for high-rate scalar quantization. Our r...

In the classical Shannon/Nyquist sampling theorem, information is not lost in uniformly sampling a signal, signal must be sampled at least two times faster than its bandwidth. Because of the restriction of the Nyquist rate, it end up with too many samples in many applications, and it becomes a great challenge for further transmission and storage. In recent years, an emerging theory of signal ac...

Inertial sensor calibration plays a progressively important role in many areas of research among which navigation engineering. By performing this task accurately, it is possible to significantly increase general performance by correctly filtering out the deterministic and stochastic measurement errors that characterize such devices. While different techniques are available model remove errors, ...
