Multi-receiver Wiretap Channel with Public and Confidential Messages
Ersen Ekrem, Sennur Ulukus
We study the multi-receiver wiretap channel with public and confidential messages. In this channel, there is a transmitter that wishes to communicate with two legitimate users in t…
Capacity-Equivocation Region of the Gaussian MIMO Wiretap Channel
Ersen Ekrem, Sennur Ulukus
We study the Gaussian multiple-input multiple-output (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the transmitt…
Capacity Region of Gaussian MIMO Broadcast Channels with Common and Confidential Messages
Ersen Ekrem, Sennur Ulukus
We study the two-user Gaussian multiple-input multiple-output (MIMO) broadcast channel with common and confidential messages. In this channel, the transmitter sends a common messag…
An Alternative Proof for the Capacity Region of the Degraded Gaussian MIMO Broadcast Channel
Ersen Ekrem, Sennur Ulukus
We provide an alternative proof for the capacity region of the degraded Gaussian multiple-input multiple-output (MIMO) broadcast channel. Our proof does not use the channel enhance…
