On The Physical Layer Security Under κ-μ Shadowed Fading Channels With Diversity Approaches

This paper presents a investigation on the performance of security under κ-μ shadowed fading channels using the Wyner’s classic wiretap model. A better fit was presented for the κ-μ shadowed fading channel curves in relation to other fading models, as Rayleigh and Nakagami-m. Results and analyses are obtained through the Secrecy Outage Probability, the Strictly Positive Secrecy Capacity and Average Secrecy Capacity curves by varying the intruder and main channel characteristics. Also, some types of diversity techniques are analysed as the Select Combining, the Maximum Ratio Combining and the MIMO with the κ-μ shadowed fading channel to obtain safer environments. Keywords—Physical Layer Security, κ-μ shadowed fading channel, Diversity Techniques, Security Metrics.
