Book excerpt: The text contains all the essential elements of communication principles, devices, circuits, antennas, and systems covering the electromagnetic spectrum from KHz to MHz of radio frequency (RF) that was developed in the formative stage of wireless technology. Also, the digital revolution, that has changed the landscape of modern electronics for wireless technology, has been discussed emphasizing the fundamentals including digital computers. The presentation of the book is in a concise yet complete way and stresses the physical and technical aspects with application viewpoints but using minimum possible mathematics. The book: Discusses the historical background of different developments of wireless technology from KHz to MHz and going through the GHz to THz in due perspective to provide a holistic view of the development of wireless technology from its inception to contemporary times. Contains in brief the basic concepts of electromagnetism like Maxwell’s wave equation, evanescent waves, surface waves, plasmonic waves that are used in wireless technology in some form or the other. Highlights the need for modulation and covers various modulation techniques such as continuous wave and pulse analogue modulation and modulation/demodulation systems that were developed in the formative stage of the development of wireless technology in the RF frequency range of KHz to MHz. Discusses the physical concepts and application view-points of active devices, RF transmission lines, antennas and systems used at KHz to MHz frequency domain of wireless technology. Covers the digital revolution that has changed the wholesale electronic systems of modern wireless technology, and the development of digital computers has also been discussed with a brief overview of laptops, supercomputers, and upcoming quantum computers. This overall scenario of historical perspective of wireless technology from KHz to THz and technical developments from KHz to MHz in the RF domain during the formative stage of development of wireless technology including fundamental developments related to digital revolution is expected to attract the interest of the entry level students, research scholars, professionals, and even the general readers alike with a new vision to have a quick yet in-depth glimpse of the progress of wireless technology since its inception till today. It is primarily written for junior undergraduate students in the fields of electrical engineering, electronics and communication engineering, wireless communication, telecommunication, and computer engineering. Research scholars and professionals can also refresh their idea of the developments of wireless technology during its formative stage and can get a flavour of the route to modern developments that have taken place henceforth.

Download or read book Radiophysical and Geomagnetic Effects of Rocket Burn and Launch in the Near the Earth Environment written by Leonid F. Chernogor and published by CRC Press. This book was released on 2013-11-13 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Radiophysical and Geomagnetic Effects of Rocket Burn and Launch in the Near-the-Earth Environment describes experimental and theoretical studies on the effects of rocket burns and launchings on the near-the-Earth environment and geomagnetic fields. It illuminates the main geophysical and radiophysical effects on the ionosphere and magnetosphere surrounding the Earth that accompany rocket or cosmic apparatus burns and launchings from 1,000 to 10,000 kilometers. The book analyzes the disturbances of plasma and the ambient magnetic and electric fields in the near-Earth environment from rocket burns and launchings from Russia, Kazakhstan, the United States, China, France, and other global space centers. Describing the radiophysical effects of rocket burn and launching in the middle and upper ionosphere, it focuses on the ecological consequences of space exploration—detailing methods for eliminating the harmful effects of space exploration. Measurements for the studies presented in the book were carried out using numerous radiophysical methods and techniques, including HF Doppler radar, incoherent and coherent scatter radar systems, microwave radar, magnetometer, and optical instrumentation and spectroscopy. The book analyzes the effects of rocket burns and launchings from 1975 to 2010 in worldwide launch campaigns. This book is an ideal reference for scientists in geophysics and radiophysics, specialists in rocket launching, and ecologists. It is also suitable as a fundamental handbook for graduate and postgraduate students taking physics and cosmic sciences courses at the university level.

Download or read book Digital Microwave Communication written by George Kizer and published by John Wiley & Sons. This book was released on 2013-05-22 with total page 756 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first book to cover all engineering aspects of microwave communication path design for the digital age Fixed point-to-point microwave systems provide moderate-capacity digital transmission between well-defined locations. Most popular in situations where fiber optics or satellite communication is impractical, it is commonly used for cellular or PCS site interconnectivity where digital connectivity is needed but not economically available from other sources, and in private networks where reliability is most important. Until now, no book has adequately treated all engineering aspects of microwave communications in the digital age. This important new work provides readers with the depth of knowledge necessary for all the system engineering details associated with fixed point-to-point microwave radio path design: the why, what, and how of microwave transmission; design objectives; engineering methodologies; and design philosophy (in the bid, design, and acceptance phase of the project). Written in an easily accessible format, Digital Microwave Communication features an appendix of specialized engineering details and formulas, and offers up chapter coverage of: A Brief History of Microwave Radio Microwave Radio Overview System Components Hypothetical Reference Circuits Multipath Fading Rain Fading Reflections and Obstructions Network Reliability Calculations Regulation of Microwave Radio Networks Radio Network Performance Objectives Designing and Operating Microwave Systems Antennas Radio Diversity Ducting and Obstruction Fading Digital Receiver Interference Path Performance Calculations Digital Microwave Communication: Engineering Point-to-Point Microwave Systems will be of great interest to engineers and managers who specify, design, or evaluate fixed point-to-point microwave systems associated with communications systems and equipment manufacturers, independent and university research organizations, government agencies, telecommunications services, and other users.
