Structured Channel Covariance Estimation from Limited Samples for Large Antenna Arrays
Tianyu Yang, Mahdi Barzegar Khalilsarai, Saeid Haghighatshoar +1
In massive multiple-input multiple-output (MIMO) systems, the knowledge of the users' channel covariance matrix is crucial for minimum mean square error (MMSE) channel estimation i…
Achievable Regions and Precoder Designs for the Multiple Access Wiretap Channels with Confidential and Open Messages
Hao Xu, Tianyu Yang, Kai-Kit Wong +1
This paper investigates the secrecy capacity region of multiple access wiretap (MAC-WT) channels where, besides confidential messages, the users have also open messages to transmit…
Quantization-Aided Secrecy: FD C-RAN Communications with Untrusted Radios
Omid Taghizadeh, Tianyu Yang, Hiroki Iimori +3
In this work, we study a full-duplex (FD) cloud radio access network (C-RAN) from the aspects of infrastructure sharing and information secrecy, where the central unit utilizes FD…
New challenges in covariance estimation: multiple structures and coarse quantization
Johannes Maly, Tianyu Yang, Sjoerd Dirksen +2
In this self-contained chapter, we revisit a fundamental problem of multivariate statistics: estimating covariance matrices from finitely many independent samples. Based on massive…
Information Bottleneck for a Rayleigh Fading MIMO Channel with an Oblivious Relay
Hao Xu, Tianyu Yang, Giuseppe Caire +1
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel with an oblivious relay. The relay is constrained to op…
Information Bottleneck for an Oblivious Relay with Channel State Information: the Vector Case
Hao Xu, Tianyu Yang, Giuseppe Caire +1
This paper considers the information bottleneck (IB) problem of a Rayleigh fading multiple-input multiple-out (MIMO) channel. Due to the bottleneck constraint, it is impossible for…
