Abstract

Today, the buzzword is high
-
data rate wireless connectivity without mobility constraints.
The provision of high rates to users, anytime and everywhere is challenged by the
timevarying wireless medium and dynamic nature of interference. Primarily, this
chal
lenge is directly related to the limited radio resources, spectrum in particular, and
energy (i.e., power) to a certain extend. Therefore, a practical resource management
method, in the form of power control, that can address system interference and thus
i
mprove spectrum utilization is presented. The proposed scheme is tested in a wireless
network that employs Orthogonal Frequency Division Multiple Access (OFDMA)
technique. The simulated results reveal that a significant improvement in capacity is
obtained
on top of the conventional water
-
filling algorithm. Our study is informed by the
fact that most current and future wireless networks (e.g., WiMAX, LTE, LTE
-
advanced)
are based on OFDMA technology. © 2009 IEEE.
