In wireless cellular or ad hoc networks where Quality of Service (QoS) is interference-limited,
a variety of power control problems can be formulated as nonlinear optimization with a …

We discuss the variational inequality problem for a continuous operator over the fixed point
set of a nonexpansive mapping. One application of this problem is a power control for a …

The authors consider a multirate code-division multiple acess system, in which all users
have the same chip rate and vary their data rate by adjusting the processing gain. The …

Nonlinear convex optimization has provided both an insightful modeling language and a
powerful solution tool to the analysis and design of communication systems over the last …

The rapid progress of mobile, wireless communication and embedded micro-sensing MEMS
technologies has brought about the rise of pervasive computing. Wireless local-area …

Uplink scheduling in wireless systems is gaining importance due to arising uplink intensive
data services (ftp, image uploads etc.), which could be hampered by the currently in-built …

Accurate power control is an essential requirement in the design of cellular code-division
multiple-access (CDMA) systems. In this paper, we contribute three main themes to the …

The quality of service in direct-sequence code-division multiple access (DS-CDMA) can be
controlled by a suitable selection of processing gain and transmission powers. In this paper …

We study the weighted sum rate maximisation problem of wireless networks consisting of
multiple source–destination pairs. The optimisation problem is to maximise a weighted sum …

Information travels in two directions in a wireless network: uplink (mobileto-base) and
downlink (base-to-mobile). The mathematical formulations of these problems are similar in …
