Abstract: A wireless secure communication method based on RIS-NOMA under complex channel conditions, the method including: firstly, an intelligent surface is assume to be disposed between the base station and legitimate NOMA users, and between the base station and eavesdroppers; the signal to interference plus distortion noise ratio (SIDNR) for the legitimate NOMA user and the eavesdropper is calculated in the presence of RHI in the system; secondly, considering shadow fading and to simplify the overly complex calculation process, the probability density function and cumulative distribution function of the shadow fading are approximated; finally, the outrage probability and intercept probability of the legitimate users and eavesdroppers are calculated.
