Some Techniques in Universal Source Coding and Coding for Composite Sources

We consider three problems in source coding. First, we consider the composite source model. A composite source has a switch driven by a random process which selects one of a possible set of subsources. We derive some convergence results for estimation of the switching process, and use these to prove that the entropy of some composite sources may be computed. Some coding techniques for composite sources are also presented and their performance is bounded.
