Design of Multiuser Intermediate Relay Safety Communication Based on Sharing Signals Subspace Beamforming
In the multiple-input multiple-output (MIMO) Gaussian K-users relay interference channel, each user intends to convey a multicast message to all other users while receiving K-1 independent messages from the other users via an intermediate relay. We come up with an encoding and decoding strategy inspired from cryptography theory. The proposed encoding and decoding strategy involves a signal space alignment for an encryption message for the multiple access phase and zero forcing with successive network code decoding for the broadcast phase. All users cooperatively choose the precoding vectors to transmit the message so that relay can receive a proper encryption message. During the broadcast phase, all users to decipher the encryption message from the relay.
