TL;DR: This work presents an accurate approximation and upper bounds for the bit error rate of the probability distribution function of the channel fading between a base station, an array of intelligent reflecting elements, known as large intelligent surfaces (LIS), and a single-antenna user.

TL;DR: This paper presents a simple and practical channel estimator for multipath multi-cell massive MIMO time division duplex systems with pilot contamination, which poses significant challenges to channel estimation.

TL;DR: A simple and practical channel estimator for multi-cell MU massive MIMO time division duplex (TDD) systems with pilot contamination in flat Rayleigh fading channels, which performs asymptotically as well as the minimum mean square error (MMSE) estimator with respect to the number of antennas.

TL;DR: In this article, the performance of a single-input single-output (SISO) system in which an LIS acts as a controllable scatterer is evaluated.

TL;DR: Spectrum Prediction Collision Avoidance (SPCA) is presented, an algorithm that can predict the behavior of other surrounding networks, by using supervised deep learning; and adapt its behavior to increase the overall throughput of both its own Multiple Frequencies Time Division Multiple Access network as well as that of the other neighboring networks.
