Abstract:
In the last two decades, a number of fundamental and
practical results have been obtained in the area of convex
optimization theory. It is a well-developed area, both in
the theoretical and practical aspects, and the engineering
community has greatly benefited from these recent advances
by finding applications. In the recent and upcoming years,
special issues in top journals and magazines on applications
of convex optimizations are being organized, as well as
edited and authored books on convex optimization and its
applications.
This tutorial will first introduce the basic theory and then
illustrate its use with some recent applications in
communication systems. The emphasis will be on i) the art of
unveiling the hidden convexity of problems by appropriate
manipulations, and ii) a proper characterization of the
solution either analytically or algorithmically. The
contents of the tutorial include A primer on convex
optimization (convex sets, convex functions, convex
problems, classes of convex problems, KKT optimality
conditions), GP with applications in power control in
wireless systems, Dual decomposition with applications in
iterative waterfilling algorithms and network utility
maximization
