摘要
干扰对准技术是一项新兴的干扰抑制技术.在MIMO系统中,干扰对准能够显著提高系统的复用增益.该文介绍了干扰对准技术的基本原理以及波束成型矩阵的限制条件,并且讨论了干扰对准在3用户MIMO系统中的应用情况.
Interference alignment is a new technique of interference suppression.It permits the network of MIMO system to achieve the optimal multiplexing gain.In this paper,we introduce the basic principals of the interference alignment,the constraint of the transmit beamforming matrix and the application of interference alignment in three users MIMO system.
