A Review of Enhance the Secrecy Performance using PLS Approach

In this paper we review the secrecy performance of cooperative non orthogonal multiple access networks at the BS for both a single-antenna and multiple-antenna for downlink and Uplink scenario. A preserved zone, also called as a wire tapper prohibition zone, is applied in all cases to improve the PLS. In the multiple-antenna aided situation, we also look at the generated noise at the BS to see if we can improve the secrecy performance even more. PLS is used to improve the secrecy performance of wireless communication systems while also increasing their bandwidth.
