Abstract-
Code-Division Multiple-Access (CDMA) is emerging as a
potential multiple access method for digital wireless
communications. CDMA has properties that make it well
suited for bursty or fading channels with cellular
topologies, making CDMA particularly attractive for
applications such as mobile telephony and personal
communications. In this talk, CDMA systems will be
reviewed. In addition, design issues and solutions for CDMA
systems offering multiple data rates will be considered.
Wireless multi-rate systems are necessary in order to
accommodate a variety of potentially disparate sources such
as voice, data and video. Maximum-likelihood based
detection schemes as well as sub-optimal schemes based on
minimum-mean squared error criteria will be investigated for
multi-rate reception. Current work on cyclic Wiener filters
for multi-rate systems will also be reviewed.
