In this dissertation, adaptive power control for single and multiuser opportunistic
systems is investigated. First, a new adaptive power-controlled diversity combining
scheme for single user systems is proposed, upon which is extended to the multiusers
case. In the multiuser case, we first propose two new threshold based parallel multiuser
scheduling schemes without power control. The first scheme is named on-off
based scheduling (OOBS) scheme and the second scheme is named switched based
scheduling (SBS) scheme. We then propose and study the performance of thresholdbased
power allocation algorithms for the SBS scheme. Finally, we introduce a unified
analytical framework to determine the joint statistics of partial sums of ordered RVs
with i.i.d. and then the impact of interference on the performance of parallel multiuser
scheduling is investigated based on our unified analytical framework.
