In this paper a K user Multi-Input Single-Output (MISO) InterFerence Channel (IFC) is considered where the interference at each receiver is treated as an additional Gaussian noise contribution (Noisy IFC). The authors address the MISO DownLink (DL) beamformer design and power allocation for maximizing the minimum SINR with per base station power constraints and imposing a minimum Quality of Service (QoS) requirement for each receiver. They study a distributed iterative algorithm for solving the given beamforming problem based on a combination of duality principles and the property that max-min SINR problem is strictly related to the total power minimization problem.
