| 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.
This textbook originates as an adaptation for undergraduate study of the wellknown
book CDMA, Principles of Spread Spectrum Communication by A.J.
Viterbi and is based on courses which I taught several years at Lund University
in Sweden. The reader can see an indubitable influence of Viterbi’s book on
the content of this book. In particular, our treatment of direct-sequence CDMA
follows the ideas and methods of Viterbi’s book, but for completeness we also
include in the book a consideration of frequency hopping CDMA and pulse
position hopping (“time hopping”) CDMA. We have studied also in more detail
forward transmission in the direct-sequence CDMA system. Furthermore, we
consider it necessary to include in our textbook information-theoretical analysis
of CDMA communication. |
