Embodiment
[0029] This embodiment provides a method for optimizing the maximum safe rate of a NOMA-based wireless portable energy communication system, the method comprising the following steps:
[0030] Step 1. Deploy a single-antenna cell base station BS, M information receivers IR and K energy receivers ER in the NOMA-based wireless energy carrying communication system, where ER obtains energy from the signal transmitted by the BS, and can Eavesdropping on the confidential information sent by the BS to the IR; the channel model used in this embodiment is a large-scale fading model, as shown in the formula: where d m =80m, means the distance from IR to BS, α=3 means path fading coefficient, v m ~CN(0,1) is the Rayleigh fading channel gain; where d k =80m, indicates the distance between ER and BS, α=3 indicates path fading coefficient, v k ~CN(0,1) is the Rayleigh fading channel gain; the above channel parameters are independent of each other, and each element is a complex Gaussia...
