Interference Alignment is an effective technique to reduce interference in a wireless system. This paper proposes an alignment based interference cancellation scheme for a multi-cell network with multiple-input multiple-output users under Gaussian Interference Broadcast Channel scenario. We focus the description on a three cell network scenario and design transmit beamforming matrix using a non-iterative closed-form approach. This approach utilizes the possibility to split up the role of the transmit beamforming matrix according to the type of interference caused by a base station. Simulation results confirm the theoretical findings and demonstrate that the proposed scheme can achieve the (L-1) degrees of freedom for each user.
