Embodiment Construction

[0062] The invention will be further described below in conjunction with the accompanying drawings.

[0063] combined with figure 1 The specific steps of the method of the present invention are described as follows.

[0064] Step 1, set resource allocation parameters.

[0065] Set the error tolerance ξ, and its value range is (0,1); set the maximum number of iterations N of secondary user security energy efficiency, and its value is a positive integer greater than 10 within the allowable counting range of the selected computing device. According to the required error tolerance and the maximum number of iterations required, set the error tolerance ξ>0 and the maximum number of iterations N. In the embodiment of the present invention, the error tolerance ξ is set to 0.0001, and the maximum number of iterations N is 100,000. The smaller the error tolerance, the more iterations may be needed when the iterative calculation system calculates the energy efficiency, but the optimal...
