Title
Sum-Rate Improved Interference Alignment for the M x 2 MIMO X Channel.
Abstract
In this letter, we propose an improved interference alignment (IA) scheme for the M 2 constant multiple-input multiple-output (MIMO) X channel composed of M transmitters and two receivers with multiple antennas each. The proposed IA scheme enhances the sum rate as well as achieving the DOF outerbound. To enhance the sum rate, the proposed scheme designs the transmit beamformers that make the desired signal space and the interference space as close to orthogonal as possible. Simulation results show that the proposed IA scheme achieves similar sum rate as the random search scheme but with less computational complexity.
