Analysis of a General Mixed Strategy for Gaussian Multiple Relay Channels
— In their landmark paper Cover and El Gamal proposed different coding strategies for the relay channel with a single relay supporting a communication pair. These strategies are ...

To Code or Not To Code in Multi-Hop Relay Channels
Multi-hop relay channels use multiple relay stages, each with multiple relay nodes, to facilitate communication between a source and destination. Previously, distributed space-tim...

Approximate Capacity of Gaussian Relay Networks
We present an achievable rate for general Gaussian relay networks. We show that the achievable rate is within a constant number of bits from the information-theoretic cut-set uppe...

A secrecy game with an informed jammer relay
A four terminal Gaussian network composed of a source, a destination, an eavesdropper and a jammer relay is investigated when the jammer relay is causally given the source message....

Achievable throughput of multiple access spectrum systems based on cognitive relay
Cognitive relays form a special cooperation relationship among users in cognitive radio networks, and help increase the transmission rates of both primary users and secondary user...
