Cooperation and opportunism are two concepts that have recently revolutionized the design of wireless systems. Successful
incorporation of these concepts in wireless system standards requires the solution of difficult theoretical and practical problems.
The main objectives of the project are:
- To explore performance limits of cooperative and opportunistic schemes (e.g. information theoretic analysis of combined
cooperative-opportunistic schemes, large-system analysis for gain quantification of cooperative schemes) and multiuser
diversity with limited feedback.
- To develop efficient strategies and coding schemes for cooperative and opportunistic communications, maximizing diversity
and coding gain under various operational scenarios (homogeneous versus inhomogeneous channel statistics, full versus
partial channel knowledge, codes for a combined cooperative-opportunistic scenario).
- To develop efficient resource allocation with limited feedback, including decentralized resource allocation, by targeting the
optimal exploitation of various grades of channel information at the transmitters (full, partial, statistical).
- To implement selected cooperative and opportunistic schemes on a testbed, in order to fully understand practical implementation
constraints, assess the benefits of cooperation and opportunism in realistic environments, and support proof-of-concept.
