Dynamic Spectrum Sharing with Limited Network State Information

Abstract

This project is concerned with the costs and benefits of learning and exchanging Network State Information (NSI) among cooperative nodes in a wireless network. NSI includes Channel State Information (CSI), along with information about quality of service requests. This report summarizes our main results on interference management and wireless resource allocation with limited information exchange. We introduce interference prices for optimizing powers and beams in an interference network with multiple antennas per node. We also discuss the performance of limited feedback schemes for multi-carrier and Multi-Input Multi-Output (MIMO) channels. Additional topics discussed include distributed power allocation(over sub-channels), beamforming, and interference cancellation in a peer-to-peer network, overhead for random network coding with unreliable links, and adaptive techniques for achieving interference alignment in MIMO interference networks.
