This paper mainly describes the transmission reliability and physical layer security of multiantenna decode-and-forward relay networks over κ - id="M4"> μ shadowed fading distribution. We consider existence residual hardware impairments (RHIs) channel estimation errors (CEEs) at same time. Firstly, we give network model. On this basis, analyze by deriving exact expressions outage probability (OP) intercept (IP). To further verify investigate theoretical derivation, approximate analysis OP is obtained under high signal-to-noise ratio. In addition, also use an optimized antenna selection technology transmitter to improve performance. Finally, through comparative study simulation Monte Carlo results, factors affecting are acquired. The interesting conclusion that both RHIs CEEs can increase decrease IP; say, reduce enhance security.
