On the Performance of Cooperative Wireless Fixed Relays in Asymmetric Channels
Abstract— In many scenarios the commonly assumed symmetry in multiple relay channels is unrealistic. Therefore, this paper, through analytical and simulation efforts, investigate...

Scaling laws of multiple antenna group-broadcast channels
Broadcast (or point to multipoint) communication has attracted a lot of research recently. In this paper, we consider the group broadcast channel where the users' pool is divi...

Superimposed XOR: A New Physical Layer Network Coding Scheme for Two-Way Relay Channels
— We present a new physical layer network coding (PLNC) scheme, called superimposed XOR, for two-way relay channels. The new scheme specifically takes into account the channel a...

On the Secrecy Capacity of Fading Channels
We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of...

Opportunistic Feedback in OFDMA Downlink
—This paper presents an opportunistic feedback (OF) protocol that reduces the amount of channel-state-information (CSI) feedback for the OFDMA downlink system. The OF protocol as...
