Adamy D. Practical Communication Theory

2nd ed. — New Jersey : SciTech Publishing, 2014. — 176 p.Practical Communication Theory, 2nd Edition enables the reader to quickly and easily generate the answers to real-world problems encountered in specifying, testing, and fielding any type of systems that involve radio propagation. It deals with free space radio propagation and propagation near the ground and over the ridge lines. As a bonus, this book also includes a special antenna and propagation slide rule, with unique scales, along with detailed explanations, and examples, of how to use it. Now in its second edition, Practical Communication has been updated to include new material on radio propagation near the earth in communication bands, which also explains how to use the slide rule scales for each of the appropriate propagation modes. The section on dynamic range has been expanded and there is additional material on knife-edge diffraction. The appendices have also been updated to include extra propagation formulae and graphs.Preface to the First Edition
The key to understanding many important fields—wireless communication, television broadcasting, radar, remote control, data links, and electronic warfare to name just a few—is a practical understanding of radio propagation. You probably don’t care how radio waves propagate, but before you can specify or design any type of equipment that generates or receives radio signals—or determine whether or not it will dependably do its job in a new situation—you will need to be able to predict what a transmitted signal will look like when it gets to a receiver as a function of frequency, distance, weather, and interference. This book will provide you with practical working tools to do just that without getting into the intimidating mathematical expressions with which these considerations are explained in most communication theory texts. There are no integral signs in this book.
