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