Channel coding and decoding in a relay system operated with physical-layer network coding

Shengli Zhang, S. Liew
Computer Science, Mathematics
IEEE Journal on Selected Areas in Communications
29 July 2008

This paper investigates link-by-link channel-coded PNC (physical layer network coding), in which a critical process at the relay is to transform the superimposed channel- coded packets received from the two end nodes (plus noise) to the network-coded combination of the source packets, S<sub>1</sub> oplus S <sub>2</sub>.

Computer Science
2nd International Conference on Broadband…
3 October 2005

We propose a new automatic rate fallback algorithm that can differentiate the two types of frame losses due to link errors and collisions over the wireless link can coexist and severely degrade the performance of the existing rate adaptation algorithms. Expand

Improving Throughput and Fairness by Reducing Exposed and Hidden Nodes in 802.11 Networks
