This state-of-the-art text provides the reader with not only the basic theory behind frequency hopping spread spectrum systems and their practical uses, but also block diagrams, circuit diagrams, plus parts lists required for building a frequency hopping radio system. Text discusses early experiments with frequency hopping systems, then turns to modern configurations to enable the reader to see frequency hopping systems in their simplest form as well as the progression to more complicated designs. Manufacturers' data sheets are included in the text to show the evolution in component design over an approximate ten-year period. FCC rules and regulations pertaining to spread spectrum activity are reproduced in an appendix. From the viewpoint of practical, hands-on construction of a frequency hopping system, this is an invaluable book.
