Selfishness and Altruism on the MISO Interference Channel: The Case of Partial Transmitter CSI
2009 (English)In: IEEE Communications Letters, ISSN 1089-7798, Vol. 13, no 9, 667-669 p.Article in journal (Refereed) Published
We study the achievable ergodic rate region of the two-user multiple-input single-output interference channel, under the assumptions that the receivers treat interference as additive Gaussian noise and the transmitters only have statistical channel knowledge. Initially, we provide a closed-form expression for the ergodic rates and derive the Nash-equilibrium and zero-forcing transmit beamforming strategies. Then, we show that combinations of the aforementioned selfish and altruistic, respectively, strategies achieve Pareto-optimal rate pairs.
