The Impact of CSI and Power Allocation on Relay Channel Capacity and Cooperation Strategies
Capacity gain from transmitter and receiver cooperation are compared in a relay network where the cooperating nodes are close together. Under quasi-static channels, when all nodes...

Cooperation strategies for secrecy in MIMO relay networks with unknown eavesdropper CSI
We investigate secure communications for a four-node relayeavesdropper channel with multiple data stream transmission, assuming that the eavesdropper’s channel state information...

Impact of CSI on Distributed Space-Time Coding in Wireless Relay Networks
We consider a two-hop wireless network where a transmitter communicates with a receiver via M relays with an amplify-and-forward (AF) protocol. Recent works have shown that sophis...

Power Allocation in MMSE Relaying over Frequency-Selective Rayleigh Fading Channels
Abstract--This paper develops an amplify-and-forward relaying scheme for multiuser wireless cooperative networks under frequency-selective block-fading. Single-carrier frequency di...

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...
