- Abstract
- In this paper, we consider network-coded bi-directional relaying (NCBR) schemes over an asymmetric channel,in which bi-directional links have the different channel quality, as well as the asymmetric traffic load. In order to deal with asymmetric nature, two different types of NCBR schemes are considered: network coding after padding (NaP) and network coding after fragmentation (NaF). Even if NaP has been known as only a useful means of dealing with the asymmetry in traffic load up to now, our analysis shows that its gain can be significantly lost by the asymmetry in channel quality, under the given bit error performance constraint.
Furthermore, it is shown that NaF always outperforms NaP, as well as traditional bi-directional relaying scheme.
