Simultaneous Diagonalization: On the DoF Region of the K-user MIMO Multi-way Relay Channel
Anas Chaaban, Karlheinz Ochs, Aydin Sezgin
The K-user MIMO Y-channel consisting of K users which want to exchange messages among each other via a common relay node is studied in this paper. A transmission strategy based on…

The Degrees of Freedom of the MIMO Y-channel
Anas Chaaban, Karlheinz Ochs, Aydin Sezgin
The degrees of freedom (DoF) of the MIMO Y-channel, a multi-way communication network consisting of 3 users and a relay, are characterized for arbitrary number of antennas. The con…
