Evaluation of Millimeter-Wave Line-of-Sight Probability With Point Cloud Data
IEEE Wireless Communications Letters, 2016Line-of-sight (LOS) probability is an integral part of radio channel models for cellular network design and evaluation. The probability along with the pathloss models in LOS and non-LOS scenarios gives us an estimate of the cellular coverage. In this letter, we present a novel method to evaluate the LOS probability by using point cloud data obtained ...

Pointing to Azimuths and Elevations of Targets: Blind and Blindfolded-Sighted
Perception, 2014Three groups of observers pointed to target circles in a path on the ground, in two parallel rows. Participants in one group viewed the circles and then pointed blindfolded. Those in a second group were blindfolded and then touched the circles with a stick while walking past them.

Line-of-sight pointing stability for "drifting" satellites
IEEE Transactions on Aerospace and Electronic Systems, 1999Explored here is the feasibility of a new attitude control approach for satellites in high altitude elliptic orbits, in order to compensate for the effect of longitudinal periodic drift relative to the ground station. A simple attitude control technique using tethers has been proposed for achieving the fixed apparent satellite orientation with respect ...

Algorithms for determination of reflection point for line-of-sight systems
Proceedings of IEEE Singapore International Conference on Networks/International Conference on Information Engineering '93, 2002The determination of the reflection point is critical in the design of line-of-sight radio links. Various methods and procedures were proposed many years ago when long manual computations were difficult and fast digital computers were not available. This paper reviews the methods used and considers several algorithms. The solutions obtained are studied

Point-to-point transmissions, terrestrial line-of-sight links, terrestrial troposcatter links
1994This chapter will deal with microwave links (radio relay links), the technology of which is founded on the possibilities offered by the very high frequencies, 1 GHz ). > 3 mm. These two aspects make it possible to obtain both wide passbands and a very directive radiation, particularly suitable for transmitting large quantities of signals or data from ...

Adaptive Friction Compensation for Line-of-Sight Pointing and Stabilization
1993 American Control Conference, 1993This paper presents a new and practical adaptive friction compensation (AFC) technique developed at Texas Instruments for either analog or digital implementation. AFC is designed to augment conventional stabilization rate loops for the purpose of adapting to the characteristics of friction and canceling its torque disturbances before they cause LOS ...

Perceptual and Motor Skills, 1977
Near-point and far-point binocular and monocular sighting tests given 240 high and low achievers from regular classrooms at Grades 4, 8, and 12 yielded significant differences by χ 3 in distributions of near-point binocular sighting only. Twelfth-grade subjects were significantly different on

Small-Cell Wireless Backhauling: A Non-Line-of-Sight Approach for Point-to-Point Microwave Links
2012 IEEE Vehicular Technology Conference (VTC Fall), 2012In this paper we investigate the feasibility of using microwave frequencies for fixed non-line-of-sight wireless backhauling connecting small-cell radio base stations with an aggregation node in an outdoor urban environment, i.e. a typical heterogeneous network scenario.
