Exact and Asymptotic Secrecy Outage Probability of MIMO System with Hybrid Diversity Combining Techniques

Abstract

This paper presents the analytical secrecy performance of joint transmit and receive antenna selection (JTRAS), transmit antenna selection/maximum ratio combining (TAS/MRC) and transmit antenna selection/receiver antenna selection (TAS/RAS) approach over multiple-input multiple-output (MIMO) wiretap channels. The exact and asymptotic closed-form expressions for the secrecy outage probability (SOP) of JTRAS, TAS/MRC and TAS/RAS model under Nakagami-m fading channels has been evaluated.
