Abstract :
A potential global performance of dynamic spectrum allocation (DSA) that exploit adaptive antenna array interference mitigation (IM) diversity at the receiver, is analyzed for interference-limited environments with high level of frequency reuse assuming Rayleigh propagation model. The system consists of base stations (BSs) that may belong to different providers, who can optimize frequency allocation to their subscriber stations (SSs) to achieve the least impact of IM on the useful signal. The derived bounds can be used as the ultimate benchmark for coordinated and decentralized IM-based DSA algorithms.
