Transmission of common, public and confidential messages in broadcast channels with multiple antennas
Abstract-- We study the Gaussian multiple-input multipleoutput (MIMO) wiretap channel, which consists of a transmitter, a legitimate user, and an eavesdropper. In this channel, the...

Optimality of FDMA in Gaussian Multiple-Access Channels with Non-zero SNR Margin and Gap
— This paper investigates the effect of non-zero SNR margin and coding gap on the maximum sum rate and achievable rate region of the Gaussian Multiple-Access Channel (MAC). Frequ...

Rayleigh Fading Multiple Access Channel Without Channel State Information
— In this paper we determine bounds of the capacity region of a two-user multipleaccess channel with Rayleigh fading when neither the transmitters nor the receiver has channel st...

A Broadcasting Relay for Orthogonal Multiuser Channels
— This paper introduces broadcasting relay nodes for orthogonal multiuser channels. The underlying idea is that a single relay node is shared by multiple source-destination pairs...

Secure Transmission with Multiple Antennas II: The MIMOME Wiretap Channel
The capacity of the Gaussian wiretap channel model is analyzed when there are multiple antennas at the sender, intended receiver and eavesdropper. The associated channel matrices a...
