Abstract :
In this paper, a Dirty Paper Coding (DPC) based Minimum Mean Square Error (MMSE) beamforming design for a MIMO interference channel has been introduced. It includes signal leakage and linear transmit filters. At each transmitter, MMSE approach has been used comprising the signal with the interference. The simulation results show that the proposed design achieves significant reduction in mean square error (MSE) value as compared to leakage based MMSE approach. An optimal DPC strategy has been used for cancelling causal interference.
