Establishment and Solution on the Multi-user Spectrum Allocation Optimization Model
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.
