Research on Spectrum Sharing Algorithm Based on ON/OFF Channel Model

为了完善频谱共享中的定价机制,提出了基于ON/OFF信道模型的频谱共享算法。通过建立ON/OFF信道模型预测状态周期,构造认知用户的效用函数和授权用户的收益函数,通过博弈理论制定一个最优价格。实验结果表明,该算法可以完善频谱共享过程中的定价机制。

In order to perfect the pricing mechanism of spectrum sharing, the spectrum sharing algorithm based ON/OFF channel model was proposed. It predicted status period via the establishment of ON/OFF channel state period prediction model, then constructed second users＇ utility function and primary users＇ revenue function. Game theory was used to set an optimal price. The simulation results revealed that the proposed algorithm can perfect the pricing mechanism in the process of spectrum sharing.
