摘要：

In this letter, we investigate the effects of multiple antennas at a legitimate receiver and imperfect channel knowledge on secure user-scaling law in uplink multiuser wiretap networks. We generalize the conventional analysis of the secure user-scaling law for a single antenna system with perfect channel knowledge by considering multiple antennas at the receiver and the channel estimation errors.
