Decentralized dynamic spectrum allocation based on adaptive antenna array interference mitigation diversity: Algorithms and Markov chain analysis
Alexandr M. Kuzminskiy, Yuri I. Abramovich · 2009
Decentralized dynamic spectrum allocation (DSA) that exploit adaptive antenna array interference mitigation (IM) diversity at the receiver, is proposed for interference-limited environments with high level of frequency reuse. The system consists of base stations (BSs) that may belong to different providers, who can optimize uplink frequency allocation to their subscriber stations (SSs) to achieve the least impact of IM on the useful signal, assuming no control over band allocation of other BSs sharing the same bands. ldquoSelfishrdquo and ldquogood neighborrdquo decentralized DSA strategies are considered. Convergence and convergence rate of the introduced techniques are investigated by means of the theory of absorbing Markov chains.
