This paper investigates the physical layer security and data transmission in cellular networks with inband underlay Device-to-Device (D2D) communications. where there is no direct link between D2D users. We propose to apply full-duplex (FD) transmission and dual antenna selection at the D2D relay node. The relay node can simultaneously act as a friendly jammer to improve the secrecy p... https://www.marcelovicente.com/product-category/balay-paddle/
