An Achievable DoF Region for the Two-User Non-Coherent MIMO Broadcast Channel with Statistical CSI
Khac-Hoang Ngo, M.Sc.
We study the two-user non-coherent multiple-input multiple-output broadcast channel with spatially correlated Rayleigh block fading. We propose a scheme to exploit the statistical channel state information, namely, the knowledge of the covariance matrix, and derive the corresponding achievable degrees of freedom region. The main idea of the proposed scheme is based on rate-splitting, additive superposition coding, and channel training. Our result shows that statistical CSI can play an important role in enhancing the degrees of freedom of a non-coherent broadcast channel.
Khac-Hoang NGO was born in Bac Giang, Vietnam, He received the Bachelor degree in Electronics and Telecommunications from University of Engineering and Technology, Vietnam National University - Hanoi, Vietnam in 2014, and the Master degree in Advanced Wireless Communication Sytems (Master SAR) from CentraleSupélec, University of Paris-Saclay, France in 2016 (both with first class honors). During his master internship with Prof. Mari Kobayashi and Prof. Sheng Yang, he worked on coded caching in wireless networks. Since November 2016, he has been working towards his Ph.D. on the topic "Non-coherent Communications" in CentraleSupélec and Mathematical and Algorithmic Sciences Lab, Huawei Technologies France, under the supervision of Prof. Sheng Yang and Dr. Maxime Guillaud, respectively.
