Title: Quasi-convexity in action: Power and resource allocation in some orthogonal relay-assisted communication systems

Conventional wireless communication networks are based on direct communication between the nodes. However, advances in transceiver technologies are enabling nodes to collaborate with each other, or with dedicated relay stations. Collaboration offers the potential for substantial gains in a variety of important performance metrics, including the achievable data rate, and the coverage region of the network, and in response to this potential, a large number of cooperative communication schemes have been proposed. In many of these schemes, a key step towards realizing their potential is the development of computationally-efficient algorithms for determining the power and the channel resources that should be allocated to each node in the network. In this talk we will describe the development of such algorithms for some simple cooperative systems, and will discuss the opportunities to enhance these algorithms and to extend them to more sophisticated cooperative systems.
