两个用户对称多输入多输出 (MIMO) 干扰信道 (IC) 的广义自由度 (GDoF) 被表征为信道强度级别和发射机处的信道状态信息级别 (CSIT) 的函数。在这种对称设置中，每个发射机配备有 M 个天线，每个接收机配备有 N 个天线，并且两个交叉链路具有相同的强度参数 α 和相同的信道不确定性参数 β。主要挑战在于外界的证明，这是通过对齐图像集方法的推广来完成的。
The generalized degrees of freedom (GDoF) of the two user symmetric multiple input multiple output (MIMO) interference channel (IC) are characterized as a function of the channel strength levels and the level of channel state information at the transmitters (CSIT). In this symmetric setting, each transmitter is equipped with M antennas, each receiver is equipped with N antennas, and both cross links have the same strength parameter α and the same channel uncertainty parameter β. The main challenge resides in the proof of the outer bound which is accomplished by a generalization of the aligned image sets approach.
