Interference alignment (IA) is known as having a great effect on the capacity achieved at each receiver in interference channel, when used in conjunction with multiple-input multiple-output (MIMO) technology. Using coordinating base station(BS) transmission, the system generates the beamforming vector to align interference signals into confined subspace at each receiver, where the beamforming and...
Recently, to improve the capacity of cell-edge user, interference alignment (IA) is an intense research interest. We focus on the IA extended to the multiple-input multiple-output (MIMO) interference network. In this method, each coordinated transmitter generates the beamforming vector to align interference from different transmitters into confined subspace at each receiver. Then, using singular value...
Simultaneous transmission to multiple users using orthogonal beamforming, known as space-division multiple-access (SDMA), is capable of achieving very high throughput in multiple-input multiple-output (MIMO) broadcast channel. In this paper, we propose a new orthogonal beamforming algorithm to achieve high capacity performance in MIMO broadcast channel. In the proposed algorithm, the base station...
