SD-Based Low-Complexity Precoder Design for Gaussian MIMO Wiretap Channels
Hao Xu, Kai-Kit Wong, Giuseppe Caire
This paper considers a Gaussian multi-input multi-output (MIMO) multiple access wiretap (MAC-WT) channel, where an eavesdropper (Eve) wants to extract the confidential information…
Coding-Enhanced Cooperative Jamming for Secret Communication: The MIMO Case
Hao Xu, Kai-Kit Wong, Yinfei Xu +1
This paper considers a Gaussian multi-input multi-output (MIMO) wiretap channel with a legitimate transmitter, a legitimate receiver (Bob), an eavesdropper (Eve), and a cooperative…
MAC Wiretap Channels with Confidential and Open Messages: Improved Achievable Region and Low-complexity Precoder Design
Hao Xu, Kai-Kit Wong, Giuseppe Caire
This paper investigates the achievable region and precoder design for multiple access wiretap (MAC-WT) channels, where each user transmits both secret and open (i.e., non-confident…
Distributed Information Bottleneck for a Primitive Gaussian Diamond Channel with Rayleigh Fading
Hao Xu, Kai-Kit Wong, Giuseppe Caire +1
This paper considers the distributed information bottleneck (D-IB) problem for a primitive Gaussian diamond channel with two relays and Rayleigh fading. Due to the bottleneck const…
