[0042] Below with reference to accompanying drawing, technical scheme and effect of the present invention are further described:
[0043] refer to figure 1 , the application system of the present invention includes a macro base station M, E home base stations and Ω users, and the Ω users are randomly distributed within the coverage of the macro base station. Each user can only connect to one base station, and each sub-channel under the base station can only be allocated to one user. In order to improve resource utilization, the home base station and the macro base station adopt a co-channel deployment method, and the spectrum allocation of the home base station can be allocated according to the existing graph theory method: adjacent home base stations use orthogonal spectrum, and the distance is relatively long The same frequency spectrum is used between femtocells.
[0044] refer to figure 2 , the implementation steps of the present invention are as follows:
