A framework for efficient rate-power allocation for OFDM in a composite-fading environment

Abstract

We propose a framework to optimally allocate transmission resources for a digital single-user multichannel transmission link operating in a dynamically-fading wireless environment. Beginning with the statistical properties of fading phenomena observed in such channels, we demonstrate how convex optimisation theory may be harnessed for this purpose. Examples are presented to illustrate how service quality criteria may be used to dynamically identify operating points for the allocation algorithm. © 2005 IEEE.
