A novel time of arrival estimation algorithm using an energy detector receiver in MMW systems

This paper presents a new time of arrival (TOA) estimation technique using an improved energy detection (ED) receiver based on the empirical mode decomposition (EMD) in an impulse radio (IR) 60 GHz millimeter wave (MMW) system. A threshold is employed via analyzing the characteristics of the received energy values with an extreme learning machine (ELM). The effect of the channel and integration...

Recursive Estimation of Spacecraft Position and Velocity Using X-ray Pulsar Time of Arrival Measurements

The use of pulsars for spacecraft position determination has been considered since their discovery. These celestial sources provide unique signals that can be detected by sensors placed onboard spacecraft. Upon sufficient detection and processing, these signals can be used to generate range measurements with respect to an inertial reference location. Multiple measurements can be used to maintai...

Real time 3-D estimation using depth from defocus

In the recent times a great amount of interest has been shown in the area of range data acquisition for supporting 3-D scene interpretation. This paper presents an interesting approach to obtain depth information using defocusing techniques. This method involves calculating distance to points in a scene using the relative blurring between two images detected with different focal settings. These...

Real Time Estimation of 3 D Environmentwith

This paper deals with the problem of 3D structure estimation of a set of geometrical primitives in an active vision context. Our method is based on the structure from controlled motion approach which consists in constraining the camera motion in order to obtain an optimal estimation of the 3D structure of a geometrical primitive. Since this approach involves to focus on the considered primitive...
