N2 - In this paper, we investigate the secrecy outage performance of spectrum sharing multiple-input
multiple-output networks using generalized transmit antenna selection with maximal ratio combining over
Nakagami-m channels. In particular, the outdated channel state information is considered at the process of
antenna selection due to feedback delay. Considering a practical passive eavesdropper scenario, we derive the
exact and asymptotic closed-form expressions of secrecy outage probability, which enable us to evaluate the
secrecy performance with high efficiency and present a new design insight into the impact of key parameters
on the secrecy performance. In addition, the analytical results demonstrate that the achievable secrecy
diversity order is only determined by the parameters of the secondary network, while other parameters related
to primary or eavesdropper’s channels have a significantly impact on the secrecy coding gain.
