Abstract :
A new iterative method based on cooperative precoding for the two-user multiple-input single-output (MISO) interference channel (IC) is proposed. In contrast to existing methods, precoders are designed in order to maximize a lower bound of the sum rate. Useful and interference powers are exchanged between the transmitters at each iteration. Numerical results show performance improvements over non-cooperative and altruistic approaches.
