Abstract
In order to manage interference in the K-user interference channel we study optimal interference aligned solutions using a modified version of the chordal distance between the signal and the interference space as a metric. A locally optimal algorithm to optimize this distance is described. The proposed metric and algorithm are validated by an improvement in the probability of error as compared to the baseline aligned solution.
