Abstract

We explore the interference pattern of a shared channel in order to establish optimal distributed resource allocation techniques in that channel. The interference diversity gain can be achieved in time, frequency and space domain. In particular we develop resource allocation techniques to harness interference diversity gain in the frequency domain. To this end we study two approaches, namely maximizing the capacity of the primary and secondary links under received interference constraint and minimizing the transmitted power of primary and secondary links under minimum QoS guarantee constraint. We will also elaborate on the application of interference diversity in UMTS Long Term Evolution (LTE) systems.
