Overview

The use of mobile communication devices has grown phenomenally throughout the world during the last few years. With strong consumer demand to increase data delivery (large emails, browsing the Internet on wireless devices, transferring video images, etc.), engineers are faced with the challenge of enhancing CDMA to provide larger data capabilities while improving voice signals for clearer reception. In November 2001 the U.S. Federal Communications Commission released a much broader band of frequencies to wireless service providers, which will speed up the development of these systems.

Provides an overview and comparison of the code division multiple access (CDMA) systems presently being deployed for second- and third-generation cellular telephony. The authors, who are researchers for Nokia, explain the basic principles of direct-sequence spread spectrum systems, and describe the IS-95, cdma2000, 1X-EV, and wideband CDMA air interfaces and systems. The voice capacity and data rates of each system are analyzed. An appendix identifies the basic components of a CDMA transceiver.Book News, Inc.(R), Portland, OR
