Distributed Spectrum Sharing Algorithm Design and Realization

This paper studies algorithm design and realization for distributed spectrum sharing. In algorithm design, one game theory based solution, price-based distributed spectrum sharing (PDSS) algorithm is presented to achieve optimal spectrum utilization. To realize the algorithm, synchronous and sequential schemes are investigated for iterative execution of user spectrum sharing strategy. The synchronous and sequential PDSSs are studied and compared with those of iterative max SINR algorithm in spectrum efficiency and power efficiency under various spectrum and user situations. Numerical results show the advantages of price theory over general game theory and sequential realization over synchronized realization in distributed spectrum sharing application.
