Abstract	This paper deals with the design of pre-coding and decorrelation matrices in the constant MIMO interference channel. First, we propose a distributed algorithm that enables all the streams of the links in the network to reach a set of target signal to interference plus noise ratios (SINRs). Depending on the chosen SINR targets, it is shown that the algorithm performs either perfect interference alignment at the receivers or tries to strengthen the useful signal regardless of interference. In a second step, we address the choice of the target SINRs and the complexity issue of the proposed distributed algorithm. We design a semi-distributed coordination algorithm that relies on a power optimization process to choose the best combination of target SINRs and to ensure a fast convergence. The performance of the proposed coordination algorithm in terms of system sum-capacity and complexity are compared to those of minimum leakage interference alignment and MAX-SINR algorithms already existing in the literature.
