4 May 2016 | | Abstract: | This letter studies the optimal degrees of freedom (DoF) region for the
asymmetric MIMO Y channel, where each user $i$ ($i=1,2,3$), equipped with $M_i$
antennas, can exchange independent messages with the other two users via the
help of a common relay, equipped with $N$ antennas. To deal with the asymmetric
data exchange pattern within each user pair, we introduce two data exchange
patterns: pairwise data exchange (PDE) and cyclic data exchange (CDE). Our
proposed achievable scheme is to align each PDE pattern with weight $d$ into a
$d$-dimensional subspace at the relay so as to form $d$ network-coded symbols,
and to align each CDE pattern with weight $d$ into a $2d$-dimensional subspace
so as to form $2d$ network-coded symbols. With PDE and CDE patterns, we obtain
a complete characterization of the optimal DoF region of the asymmetric MIMO Y
channel. | | Source: | arXiv, 1605.1178 | | Services: | Forum | Review | PDF | Favorites | |
