摘要

本文基于寡头市场的博弈的模型对频谱分配算法进行改进,建立了基于价格机制的频谱分配系统算法。在主用户的价格函数加入频谱相似度矩阵和频谱数量总和Q,改进了主用户价格函数。对次用户的效用函数考虑了竞争带来的负面效用和传输效率对于价格的影响,改进了以寻求所有用户的最优解。通过Matlab仿真模拟明晰纳什均衡点与效用函数的变量之间的关系。
        This paper improves the spectrum allocation algorithm based on the game model of oligopoly market,and establishes a spectrum allocation system algorithm based on price mechanism. The price function of the primary user is improved by adding the spectrum similarity matrix and the sum of the number of spectrum Q to the price function of the primary user. The utility function for secondary users takes into account the negative effects of competition and the influence of transmission efficiency on price, and improves the utility function to find the optimal solution for all users. The relationship between Nash equilibrium point and utility function variables is clarified by simulation with Matlab.
