… From (12), we find that ESC is an increasing function of the transmit SNR γ0. Moreover,
using (12), we can easily calculate and compare the transmit power costs for different network …

… In this paper, we investigate the secure transmission in multi-user distributed massive MIMO
systems. To the best of authors’ knowledge, this is the first paper that considers the secure …
