Abstract

Compact Ku-band Transmitter Design for Satellite Communication Applications reviews approaches to and topologies of Ku-band transmitters. The advantages and disadvantages of these transmitters are explored along with critical design criteria necessary to enhance system performance. The design and implementation of a functional compact LTCC-based transmitter module featuring an integrated filter and MMIC chipsets are explained. Through this book, the reader will learn to analyze, design and characterize these transceiver modules. Compact Ku-band Transmitter Design for Satellite Communication Applications's strength is clearly seen in its focus on component-based design for wireless system applications. This aspect represents realistic views of today's wireless design. The book will bring essential design skills to engineers as well as references to the academic community.

Abstract

Doppler Applications in LEO Satellite Communication Systems develops and presents an important class of techniques useful in the construction of little Low Earth Orbit (LEO) satellite communication systems. 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. 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. This volume starts with a recounting of the characteristics of a LEO satellite and its orbit. The 2nd chapter addresses the LEO orbital geometry and reviews the Doppler effect attending LEO communications. Chapter three is focused on the important task of estimating the Doppler at a ground terminal. Appropriate signal processing algorithms are reviewed. Chapter four is concerned with predicting LEO satellite visibility. 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. The last chapter describes MATLAB® based analysis. Doppler Applications in LEO Satellite Communication Systems provides a thorough review of the LEO Doppler phenomenon.
