ABSTRACT:
The decode-and-forward (DF) strategy can in theory brings very interesting performance. However, achieving these performance requires a high processing at relays which is often not possible due to hardware limitations. In this talk, we present a DF protocol, the Incomplete DF (IDF), and two decoding techniques at relays, using the particular space-time code structure of TAST codes and a diophantine approximation, respectively. We show that these two methods considerably reduce complexity while keeping good performance.

BIO:
n 2005, Charlotte Hucher received both her french Engineering degree in Telecommunications and her master degree in Digital communications from TELECOM ParisTech and Université de Nice-Sophia Antipolis, respectively. In 2009 she received her PhD degree in Communications and Electronics from TELECOM ParisTech, where she was working on cooperative networks. She is a now a research fellow in the research school of information sciences and engineering (RSISE) in ANU, working on cooperative networks and mismatch decoding.
