说明：  THEORY OF CODE DIVISION MULTIPLE ACCESS COMMUNICATION The objective of this book is to provide an introduction to code division multipleaccess (CDMA) communications. Our motivation for emphasizing CDMA communication is a result of the technological developments that have occurred during the past decade. We are currently witnessing an explosive growth in wireless communication and cellular mobile radio systems, which are based on different multiple-access techniques. We anticipate that, in the near future, we will see a replacement of the current time- and frequency division methods in wireless communication and mobile radio by CDMA.
