Abstract: Considering a Multiple Input Multiple Output (MIMO) interference channel with K-user pairs, an iterative algorithm based on projection is proposed. In this algorithm, the objective function is the weighted sum of leakage of interference and desired signal out of their corresponding subspace. This algorithm can increase distance between interference subspace and desired signal subspace. Simulation results show that sum rate of the adjustable weight iteration algorithm is superior to other schemes.
