In wiretap channels the eavesdropper's channel state information (CSI) is commonly assumed to be known at the transmitter, fully or partially. In practice, the eavesdropper may not be motivated to feedback correct CSI. In this paper we consider a more practical problem for the transmitter to have the eavesdropper's CSI. That is, the fast fading multiple-antenna Gaussian broadcast channels (FMGBC-CM)...
In this paper we consider the secure transmission over the fast fading multiple antenna Gaussian broadcast channels with confidential messages (FMGBC-CM), where a multiple-antenna transmitter sends independent confidential messages to two users with information theoretic secrecy and only the statistics of the receivers' channel state information are known at the transmitter. We first use the same...
