In this thesis, we consider K-user MIMO interference channel under channel uncertainty. For improvement of performance under channel uncertainty, we set two optimization problem for each transmitter and each receiver. Proposed algorithm designs transmit beamforming matrices to minimize interference leakage. Receive beamforming matrices are designed for minimizing the worst per-stream MSE at each receiver. Proposed algorithm consider interference alignment simultaneously with improvement of sum rate performance. Through this fact, we explain the relation with minimizing the worst per-stream MSE and maximizing average sum rate. Also we explain fairness. We simulate proposed algorithm and compare the results with other interference alignment algorithm. We show that proposed algorithm has better performance on fairness and average sum rate.
