摘　　要：为解决多区域多用户在通信过程中的频谱最优分配与激励问题,本文首先在考虑多个通信运营商及多个小区用户的情况下,通过区块链理论对不同小区不同用户的频谱分配问题进行分析建模,并建立频谱最优分配优化模型;其次,针对优化模型的约束条件,通过引入拉格朗日及二分法理论对其进行求解,进而得出不同小区用户人数与频谱分配之间的数学关系;最后,通过仿真证明了容纳小区人数与频谱持有量近似地呈线性关系,且基站功率越大,近似直线的斜率越大。当基站的持有频谱量较少时,提高功率对可容纳人数的增加影响较小,随着频谱量的增加,提高基站功率,可容纳人数随之近似线性增加。In this paper,the problem of optimal spectrum allocation and excitation could be solved in the process of multi-area multi-user communication.First,the spectrum allocation problem of different users in different cells is ana-lyzed and the optimal spectrum allocation optimization model is established through the block chain theory in the case of considering multiple operators.Second,according to the constraints of the optimization model,Lagrange and Dichot-omy theory are introduced to solve it,and then the mathematical relationship between the number of users in different cells and the spectrum allocation can be obtained.Finally,the simulation proved that the number of accommodation cells and the spectrum holding capacity were approximately linear,and the greater the power of the base station,the greater the slope of the approximate straight line.When the amount of spectrum held by the base station was small,the increase of power had little impact on the increase of the number of people that could be accommodated.With the in-crease of the amount of spectrum,the increase of power of the base station would increase the number of people that could be accommodated approximately linearly.
