Beamforming on the MISO Interference Channel With Multi-User Decoding Capability

This paper considers the Multiple-Input-Single-Output Interference Channel (MISO-IC) in which transmitters and receivers share the same time and frequency resources. The authors consider receivers with Interference Decoding Capability (IDC) so that the interference signal can be decoded and subtracted from the received signal. On the MISO-IC with single user decoding, transmit beamforming vectors are designed to mitigate interference at the receivers. With IDC, receivers can potentially decode interference which yields a higher data rate. Yet, decoding interference poses a rate constraint on the interferer and in turn on the sum rate of the system.
