- Moreover, we derive the solution to the latter subproblem, that we dub non-homogeneous waterfilling (a variation on the MIMO waterfilling solution), and underline an inherent desirable feature: its ability to turn-off streams exhibiting low-SINR, thereby greatly speeding up the convergence of the proposed algorithm.2016, Hadi Ghauch, Taejoon Kim, Mats Bengtsson, Mikael Skoglund, “Separability and Sum-Rate Maximization in MIMO Interfering Networks”, in arXiv:
