Dominant path model fitted to signal measurements of digital TV in non-line of sight propagation

2017 IEEE Radio and Antenna Days of the Indian Ocean (RADIO), 2017
Broadcast television is one of the most important telecommunication systems in Brazil. Such relevance requires that an assessment of the coverage and quality of the Digital TV signal must be extensively performed in the pursuit of technical excellence.

A TOA-based location algorithm reducing the errors due to non-line-of-sight (NLOS) propagation

IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002
An effective location algorithm, which considers non-line-of-sight (NLOS) propagation, is presented. By using a new variable to replace the square term and adding the loose variable, the problem becomes a mathematical programming problem, and then the NLOS propagation's effect can be evaluated.

Optical scattering communication under various aerosol types based on a new non-line-of-sight propagation model

Optik, 2018
Abstract This paper proposes a model for non-line-of-sight (NLOS) single-scatter propagation in an inhomogeneous atmosphere. This propagation model is used to simulate optical scattering communication under various atmospheric aerosol types. In the traditional NLOS propagation model, the atmosphere is assumed to be homogeneous.
