Generalized Transmission Scheme for Mimo Y Channel

This paper proposes a novel scheme for a multi-way communication where users combine bi-directional multi-pair messages exchange with multi-directional multi-pair exchange. Particularly, we focus on the system where multiple users have multiple antennas exchange both private and common messages with each other. In this scheme, we can use simple zero forcing combined with successive network code decoding enables all user to decipher the encryption message from the relay despite the fact that they all have different self-information which they use as a key.
