![]() ![]() The last chapter describes MATLAB(R) based analysis.ĭoppler Applications in LEO Satellite Communication Systems provides a thorough review of the LEO Doppler phenomenon. The curve of Doppler-Shift and Doppler-Rate when the Doppler effect is severe is shown in Figure 1. Chapters five and six are, respectively, devoted to the use of the significant LEO Doppler as an aid in a new traffic flow control protocol and as an aid for effecting communications power control. Chapter four is concerned with predicting LEO satellite visibility. In a low-earth orbiting satellite, called a LEO satellite, the path loss is not such a problem, but Doppler shift and multipath problems. Appropriate signal processing algorithms are reviewed. Chapter three is focused on the important task of estimating the Doppler at a ground terminal. The shift will eventually start decreasing quickly as the satellite passes over head (this is where the doppler offset is zero and the satellite acceleration (doppler rate) is maximal) until it heads back toward the horizon and towards its maximal negative doppler shift. The 2nd chapter addresses the LEO orbital geometry and reviews the Doppler effect attending LEO communications. ![]() This volume starts with a recounting of the characteristics of a LEO satellite and its orbit. A new method for compensate influence of. Immediately after the satellite rises, relative to a particular receiver, its Doppler shift. The techniques taught in the book are expected to be particularly attractive to system engineers because ground-based transceivers must generally compensate for the large Doppler component and therefore the necessary receiver processing loops are often already in place and expensed. For low earth orbit (LEO) satellite communication, a frequency shift from the Doppler effect can cause some design difficulty of the receiver. The high Doppler effects in satellite communications make the equivalent channels fast varying, which leads to channel estimation difficulties and the need. The Doppler shift continuously changes throughout the overhead pass. It centers on the very significant Doppler shift that attends communications through a LEO satellite and shows how this phenomenon can be exploited for an unexpected benefit.
