When Physical Layer Key Generation Meets RIS: Opportunities, Challenges, and Road Ahead
Ning Gao, Yu Han, Nannan Li +2
Physical layer key generation (PLKG) is a promising technology to obtain symmetric keys between a pair of wireless communication users in a plug-and-play manner. The shared entropy…
(Non)-Coherent MU-MIMO Block Fading Channels with Finite Blocklength and Linear Processing
Junjuan Feng, Hien Quoc Ngo, Michail Matthaiou
This paper studies the coherent and non-coherent multiuser multiple-input multiple-output (MU-MIMO) uplink system in the finite blocklength regime. The i.i.d. Gaussian codebook is…
Superdirective Arrays with Finite-Length Dipoles: Modeling and New Perspectives
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +1
Dense arrays can facilitate the integration of multiple antennas into finite volumes. In addition to the compact size, sub-wavelength spacing enables superdirectivity for endfire o…
Massive Access in Extra Large-Scale MIMO with Mixed-ADC over Near Field Channels
Yikun Mei, Zhen Gao, De Mi +5
Massive connectivity for extra large-scale multi-input multi-output (XL-MIMO) systems is a challenging issue due to the near-field access channels and the prohibitive cost. In this…
Superdirective Antenna Pairs for Energy-Efficient Terahertz Massive MIMO
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +1
Terahertz (THz) communication is widely deemed the next frontier of wireless networks owing to the abundant spectrum resources in the THz band. Whilst THz signals suffer from sever…
Channel Estimation in RIS-assisted Downlink Massive MIMO: A Learning-Based Approach
Tung T. Vu, Trinh Van Chien, Canh T. Dinh +2
For downlink massive multiple-input multiple-output (MIMO) operating in time-division duplex protocol, users can decode the signals effectively by only utilizing the channel statis…
