Abstract:
Universal Mobile Telecommunication System
(UMTS) networks rely on the performance of power
control algorithms in use. The conventional power
control in UMTS is a fixed stepsize algorithm which
can achieve only limited performance. A number of
advanced power control techniques have been
presented in the literature. However, it is difficult to
compare the performance of algorithms from different
literature because they were evaluated based on
different simulation environments and assumptions. In
this paper, performance of a number of adaptive power
control algorithm is compared under the same
simulation environment and assumptions. The
simulation results show that AS-CLPC provides the
best performance for low-speed users, and SA-CLPC
provides the best performance for high-speed users.
