Bandwidth and power allocation for cooperative strategies in Gaussian relay networks
Abstract-- In a relay network with a single sourcedestination pair, we examine the achievable rates with amplifyand-forward (AF) relaying strategy. Motivated by applications in sen...

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...

Optimal Routing for Decode-and-Forward based Cooperation in Wireless Networks
Abstract- We investigate cooperative wireless relay networks in which the nodes can help each other in data transmission. We study different coding strategies in the single-source ...
