This book studies the vulnerability of wireless communications under line-of-sight (LoS) and non-LoS correlated fading environments. The authors theoretically and practically provide physical layer security analyses for several technologies and networks such as Fifth-Generation (5G) networks, Internet of Things (IoT) applications, and Non-orthogonal multiple access (NOMA). The authors have provided these under various practical scenarios, and developed theoretical aspects to validate their proposed applications.

• Presents physical layer security (PLS) under correlated fading environments, 5G wireless networks, and NOMA networks;
• Provides end-to-end analyses, combination of channel correlation and outdated CSI and their effects on PL;
• Includes contributions of PLS research written by global experts in academia and industry.
