N2 - In this paper, we develop a non-iterative transceiver design based on interference alignment (IA) for MIMO interfering broadcast channels with arbitrary number of cells and users per cell. By aligning the interference from other cells efficiently, we show that the proposed transceiver design can achieve the degrees of freedom (DOF) of d per user, i.e. total DOF of ∑ci=1 Kid, where C is the number of cells, Ki is the number of users for the i-th cell, and d is the number of streams per user. We also investigate conditions for the antenna configuration in order to attain the total DOF of ∑ci=1 K id. From simulation results, we demonstrate that the proposed transceiver design can obtain higher DOF than the conventional scheme under equal antenna configuration.
