Abstract
We advance our previously developed framework [1]-[2] for predictive dynamic transmission resource allocation for time-varying frequency-selective fading following a Hidden Markov Model (HMM) distribution, and our evaluation of the resource allocation as a convex optimization problem is presented. This treatment is extended for composite fading, incorporating additional fading effects marked by rapid development and an attendant rapidly-decaying time auto-correlation function. We then illustrate framework application in a composite fading environment exhibiting components of both fast and slowly developing fade processes. Results are presented, as well as a direction for future research.
