Rate-Splitting and Sum-DoF for the K-User MISO Broadcast Channel with Mixed CSIT and Order-(K-1) Messages
Shuo Zheng, Tong Zhang, Jingfu Li +4
In this paper, we propose a rate-splitting design and characterize the sum-degrees-of-freedom (DoF) for the K-user multiple-input-single-output (MISO) broadcast channel with mixed…
DoF Upper Bound on Three-User MISO Broadcast Channel with Two Antennas and Mixed CSIT
Shuo Zheng, Tong Zhang, Shuai Wang +4
With delayed and imperfect current channel state information at the transmitter (CSIT), namely mixed CSIT, the sum degrees-of-freedom (sum-DoF) in the two-user multiple-input multi…
Optimality of the Proper Gaussian Signal in Complex MIMO Wiretap Channels
Yong Dong, Yinfei Xu, Tong Zhang +1
The multiple-input multiple-output (MIMO) wiretap channel (WTC), which has a transmitter, a legitimate user and an eavesdropper, is a classic model for studying information theoret…
The Generalized Degrees-of-Freedom of the Asymmetric Interference Channel with Delayed CSIT
Tong Zhang, Yufan Zhuang, Yinfei Xu
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), whe…
The DoF Region of Two-User MIMO Broadcast Channel with Delayed Imperfect-Quality CSIT
Tong Zhang
The channel state information at the transmitter (CSIT) play an important role in the performance of wireless networks. The CSIT model can be delayed and imperfect-quality, since t…
