Abstract: We consider the problem of quantifying the Pareto optimal boundary in theachievable rate region over multiple-input single-output MISO interferencechannels, where the problem boils down to solving a sequence of convexfeasibility problems after certain transformations. The feasibility problem issolved by two new distributed optimal beamforming algorithms, where the firstone is to parallelize the computation based on the method of alternatingprojections, and the second one is to localize the computation based on themethod of cyclic projections. Convergence proofs are established for bothalgorithms.
