Direct versus indirect line of sight (LOS) stabilization
IEEE Transactions on Control Systems Technology, 2003Two methods are analyzed for inertially stabilizing the pointing vector defining the line of sight (LOS) of a two-axis gimbaled laser tracker. Mounting the angular rate and acceleration sensors directly on the LOS axes is often used for precision pointing applications.

Pulse detection algorithm for line-of-sight (LOS) UWB ranging applications
IEEE Antennas and Wireless Propagation Letters, 2005This paper presents an algorithm for precise determination of the distance between a pair of transmitting and receiving antennas using FCC conforming ultra-wideband (UWB) pulses. Indoor line-of-sight (LOS) measurements up to 24 m were conducted at Research Technoplaza, Nanyang Technological University, Singapore.

Abstract This paper presents the results of line-of-sight (LOS) attitude control using control moment gyros under a micro-gravity environment generated by parabolic flight. The W-Z parameters are used to describe the spacecraft attitude. In order to stabilize the current LOS to the target LOS, backstepping-based feedback control is considered using ...

Precoding for MIMO Systems in Line-Of-Sight (LOS) Environment
IEEE GLOBECOM 2007-2007 IEEE Global Telecommunications Conference, 2007In line-of-sight (LOS) environments, the signal detection of multiple-input multiple-output (MIMO) systems becomes difficult because the correlation among channels becomes higher when the phase differences of direct paths are close to each other. In this paper, we propose a MIMO system with precoding to maximize the minimum distance (denoted hereafter ...

A statistical model for line-of-sight (LOS) factory radio channels
IEEE 39th Vehicular Technology Conference, 2003A statistical model, based on experimental data, is presented to characterize the multipath propagation medium in typical manufacturing environments. This model includes the statistics of multipath propagation characteristics for cases of light and heavy clutter in a factory where there is a direct path from transmitter to receiver.

Line of Sight (LoS) Underwater Wireless Optical Communication Based on LED
2018 9th International Symposium on Telecommunications (IST), 2018In this paper, we propose a communication system for an underwater environment based on the LED. Different modulation techniques examined under pure and coastal water. A BER analyzed to assess the system with a different situation. The simulation results indicate that a LED can be operated with a good received information quality under pure sea water ...
