Finally, we phenomenologically separate phase according to magnetic fields, the results is consistent with our new idea where we use the Hamiltonian with curved surface to analyze XY model. In chapter Ⅳ, we make two hypotheses: the system has one-step time correlation and two-step time correlation.

When the launched SNR is more than the threshold, the cognitive network is an inter-user interference limited system, the base station selects the stochastic wave forming mode of a single beam and selects the user which has the maximum received SNR from the sub-scribers as a current communication object; when the launched SNR is less than the threshold, the sub-scriber network is a noise interference limited system. The base station selects the opportunistic SDMA of multi-beams and then selects a plurality of scribers with the maximum received SNR from the sub-scribers as the communication objects, thus realizing the maximization of system capacity.
