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…
On Discrete Age of Information of Infinite Size Status Updating System
Jixiang Zhang, Yinfei Xu
In this paper, for the discrete time status updating system with infinite size, we derive the explicit expression of average age of information (AoI), and the AoI's stationary dist…
New Proofs of Extremal Inequalities With Applications
Yinfei Xu, Guojun Chen
The extremal inequality approach plays a key role in network information theory problems. In this paper, we propose a novel monotone path construction in product probability space.…
On Age of Information for Discrete Time Status Updating System With Ber/G/1/1 Queues
Jixiang Zhang, Yinfei Xu
In this paper, we consider the age of information (AoI) of a discrete time status updating system, focusing on finding the stationary AoI distribution assuming that the Ber/G/1/1 q…
Age of Information in Relay-Assisted Status Updating Systems
Jixiang Zhang, Yinfei Xu
In this paper we consider the age of information (AoI) of a status updating system with a relay, where the updates are delivered to destination either from the direct line or the t…
