Abstract

Propagation characteristics while entering tunnels are analyzed by using a ray-launching technique and the uniform theory of diffraction (UTD). RMS angular spread is studied and related to the “excitation zone.” This paper presents interesting differences in the behavior of this parameter and the RMS delay spread. © 2003 Wiley Periodicals, Inc. Microwave Opt Technol Lett 37: 196–198, 2003; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.10866 [ABSTRACT FROM AUTHOR]

Abstract

This letter presents a characterization of the vertical plane propagation in terms of the satellite elevation angle for different mechanisms of propagation. The effect of blockage by buildings on the received signal level versus the satellite elevation angle at L-band for urban environments is performed using the uniform theory of diffraction (UTD). © 2000 John Wiley & Sons, Inc.
