Decentralised precoding scheme for MIMO interference channels

This reported work considers multiple-input-multiple-output (MIMO) interference channels, and a decentralised precoding scheme based on maximising the signal to weighted generated interference plus noise ratio is proposed with only locally available channel state information at each transmitter. By weighted suppression of the generated interference, each transmitter effectively achieves a balance between desired signal maximisation and weighted generated interference minimisation. Simulation results confirm that proposed precoding scheme offers significant sum rate enhancement in MIMO interference channels.
