—Massive multiple-input multiple-output (MIMO) is believed to deliver unrepresented spectral efficiency gains for 5G and beyond. However, a practical challenge arises during its commercial deployment, which is known as the “curse of mobility”. The performance of massive MIMO drops alarmingly when the velocity level of user increases. In this paper, we tackle the problem in frequency division duplex (FDD) massive MIMO with a novel Channel State Information (CSI) acquisition framework. A joint…

Matrix pencil method for estimating parameters of exponentially damped/undamped sinusoids in noise
It is found through perturbation analysis and simulation that, for signals with unknown damping factors, the pencil method is less sensitive to noise than the polynomial method.
Addressing the Curse of Mobility in Massive MIMO With Prony-Based Angular-Delay Domain Channel Predictions
A novel form of channel prediction method, named Prony-based angular-delay domain (PAD) prediction, which is built on exploiting the specific angle-delay-Doppler structure of the multipath, which relies on the high angular- delay resolution which arises in the context of 5G.
Deep Learning-Based FDD Non-Stationary Massive MIMO Downlink Channel Reconstruction
Seeing the channel as an image, You Only Look Once (YOLO), a powerful neural network for object detection, is introduced to enable a rapid estimation process of the model parameters, including the detection of angles and delays of the paths and the identification of visibility regions of the scatterers.
An efficient augmented Lagrangian method with applications to total variation minimization
An algorithm for solving a class of equality-constrained non-smooth optimization problems (chiefly but not necessarily convex programs) with a particular structure that effectively combines an alternating direction technique with a nonmonotone line search to minimize the augmented Lagrangian function at each iteration is proposed.

Channel Prediction in High-Mobility Massive MIMO: From Spatio-Temporal Autoregression to Deep Learning
Simulation results under the 3GPP non-line- of-sight (NLOS) scenarios indicate that, compared to the state-of-the-art Prony-based angular-delay domain (PAD) prediction method, both the proposed ST-AR and the CVNN-based channel prediction methods can enhance the channel prediction accuracy.
