Wireless mobile communication is witnessing a rapid growth in, and demand
for, improved technology and range of information types and services. Further,
third generation cellular networks are expected to provide mobile users with
ubiquitous wireless access to a global backbone architecture that carries a wide
variety of electronic services. We examine the topic of power control and
models that arc suitable for modem third generation wireless networks. CDMA
technology is proving to be a promising and attractive approach for spectrally
efficient, economical and high quality digital communications wireless
networks. This thesis addresses the challenge of integrating heterogeneous
transmitting sources with a broad range of Quality of Service characteristics in
the cellular COMA networks. Provided the right power control can be devised,
COMA offers the potential of extracting gain from the statistical multiplexing of
such sources. A distributed power control algorithm is proposed which is
required to update the transmitted power of the mobiles in each of the service
classes locally. and enhance the performance of the system significantly.
Algorithms for pragmatic issues like power level quantization and truncation of
power are derived and incorporated into the proposed distributed power control
algorithm. / Thesis (M.Sc.Eng.)-University of Natal, Durban, 2000.
