本文针对准静态M×2 X信道，提出了两种中继辅助干涉对准（IA）方案。第一种方案使用一个全双工中继，第二种方案使用两个半双工中继。在所提出的方案中，发射机在每个时隙中发射，继电器以放大转发（AF）模式工作。通过确认期望信号与干扰之间以及期望信号之间的线性无关性，表明所提出的方案可以实现2M/(M + 1)自由度（DoF），即M × 2x通道的最大自由度。
In this paper, two relay-aided interference alignment (IA) schemes are proposed for the quasi-static M×2 X channel. The first scheme utilizes one full-duplex relay and the second scheme utilizes two half-duplex relays. In the proposed schemes, transmitters transmit in every time slot and relays operate in amplify-and-forward (AF) mode. By confirming the linear independence between the desired signals and interference and also among the desired signals, it is shown that the proposed schemes can achieve 2M/(M + 1) degrees of freedom (DoF) which is the maximum DoF of M × 2 X channel.
