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 ...

Iterative layering: Optimizing arithmetic circuits by structuring the information flow
Current logic synthesis techniques are ineffective for arithmetic circuits. They perform poorly for XOR-dominated circuits, and those with a high fan-in dependency between inputs ...
