Coding Strategies for Bidirectional Relaying for Arbitrarily Varying Channels
In this work we study optimal coding strategies for bidirectional relaying under the condition of arbitrarily varying channels. We consider a three-node network where a relay node ...

How to beat the sphere-packing bound with feedback
The sphere-packing bound Esp(R) bounds the reliability function for fixed-length block-codes. For symmetric channels, it remains a valid bound even when strictly causal noiseless ...

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 ...

The Rate Loss of Single-Letter Characterization: The "Dirty" Multiple Access Channel
For general memoryless systems, the typical information theoretic solution - when exists - has a "single-letter" form. This reflects the fact that optimum performance ca...

Energy Efficiency of Fixed-Rate Wireless Transmissions under QoS Constraints
1 Transmission over wireless fading channels under quality of service (QoS) constraints is studied when only the receiver has perfect channel side information. Being unaware of the...
