Chapter Chapter 3 COMMERCIAL APPLICATIONS The emphasis of this book has been on the design and analysis of spread- spectrum radios for military applications. In such applications, the goal is to combat intentional jamming by an enemy transmitter. The price for using spread-spectrum radios that provide the desired AJ properties is using large-bandwidth spread-spectrum signals that result in the apparent ineffi- cient use of the radio spectrum. Owing to this apparent bandwidth ineffi- ciency, most people, including at one time the authors of this book, incorrectly assumed that commercial applications of spre
