Probabilistic Examination of Least Squares Error in Low-bitwidth Cholesky Decomposition
Alexander Osinsky, Roman Bychkov, Mikhail Trefilov +2
In this paper, we propose a new approach to justify a round-off error impact on the accuracy of the linear least squares (LS) solution using Cholesky decomposition. This decomposit…
Virtual Sectorization to Enable Hybrid Beamforming in mm-Wave mMIMO
Roman Bychkov, Andrey Dergachev, Alexander Osinsky +2
Hybrid beamforming (HBF) is a key technology to enable mm-wave Massive multiple-input multiple-output (mMIMO) receivers for future-generation wireless communications. It combines b…
Reconfigurable Intelligent Surface MIMO Simulation using Quasi Deterministic Radio Channel Model
Semyon Dorokhin, Pavel Lysov, Anastasia Aderkina +1
Reconfigurable Intelligent Surface (RIS) is a planar array that can control reflection and thus can implement the concept of partially controllable propagation environment. RIS rec…
A 2D-programmable and Scalable Reconfigurable Intelligent Surface Remotely Controlled via Digital Infrared Code
Andrey Sayanskiy, Andrey Belov, Ruslan Yafasov +4
Reconfigurable Intelligent Surfaces (RISs) are promising and relatively low-cost tools for improving signal propagation in wireless communications. An RIS assists a base station in…
