摘要：
The paper proposes a spectrum sharing algorithm based on the repeated game theory for cognitive radios. The appropriate "trigger strategy" is adopted to maximize the total rate profit of spectrum sharing and Pareto optimality. Performance analysis and simulation results show that the cooperative strategy for spectrum sharing can get the goal of total profits maximization. Next, the convergence behavior of the spectrum sharing algorithm is investigated in consideration of the impacts of the transmission power, noise power, discount factor and convergence coefficient. Finally, relevant conclusions are drawn.
