论文摘要
在本文中，我们研究了不对称干扰通道的普遍自由度（GDOF），在发射机（CSIT）上延迟了通道状态信息，其中每个发射器具有两个天线，每个接收器具有一个天线，每个干涉链的强度可能会有所不同。最佳sum-GDOF的特征是匹配的交谈和可实现性证明。通过我们的结果，我们还揭示了在天线设置中，在[Mohanty等人的对称GDOF下限。 Al，TIT 2019]可以升高，并在[Mohanty等人[Mohanty et。 Al，Tit 2019]实际上很紧。
In this paper, we investigate the generalized degrees-of-freedom (GDoF) of the asymmetric interference channel with delayed channel state information at the transmitter (CSIT), where each transmitter has two antennas, each receiver has one antenna, and the strength for each interfering link can vary. The optimal sum-GDoF is characterized by matched converse and achievability proof. Through our results, we also reveal that in our antenna setting, the symmetric GDoF lower bound in [Mohanty et. al, TIT 2019] can be elevated, and the symmetric GDoF upper bound in [Mohanty et. al, TIT 2019] is tight in fact.
