In this article, the statistical moments of the local spectrum obtained from Gabor transform technique for the chirp signal are presented both analytically and numerically. The chirp signal estimation considering only ridge frequency component and electrically band limited frequency components is also discussed.
Free Space Optics (FSO) is a promising optical technology that has a great chance to compliment the traditional wireless communications especially for applying this technology to satellite. It offers some inherent advantages compared to RF such as smaller telescopes, low power consumption, no frequency restrictions, no electromagnetic interference, and large increase in bandwidth. However, FSO is...
In this paper an adjustment factor which reflects the vertical variation of dust storm (earth satellite links) has been derived based on the analysis of the vertical dust storm behavior. The paper has been divided to four parts. First an introduction to the dust storm phenomena and its effect on microwave signal attenuation. Secondly, observations of the behavior of the vertical dust storm intensity...
