Abstract :
This paper explores practical techniques for the Slepian-Wolf (SW) source coding of correlated sources and multi-access channel (MAC) coding. Duality between these two problems is explored in the encoding/decoding framework, while concepts from turbo codes are used to achieve good performance in both cases.
