Cell-free mMIMO Support in the O-RAN Architecture: A PHY Layer Perspective for 5G and Beyond Networks
Vida Ranjbar, Adam Girycki, Md Arifur Rahman +3
To keep supporting next-generation requirements, the radio access infrastructure will increasingly densify. Cell-free (CF) network architectures are emerging, combining dense deplo…
Transfer functions of FXLMS-based Multi-channel Multi-tone Active Noise Equalizers
Miguel Ferrer, María de Diego, Gema Piñero +3
Multi-channel Multi-tone Active Noise Equalizers can achieve different user-selected noise spectrum profiles even at different space positions. They can apply a different equalizat…
GEVD-based Low-Rank Channel Covariance Matrix Estimation and MMSE Channel Estimation for Uplink Cellular Massive MIMO Systems
Robbe Van Rompaey, Marc Moonen
Uplink channel estimation is a crucial component for the performance of cellular massive MIMO systems. However, when the number of user equipments (UEs) grows, the sharing of the a…
Intersymbol and Intercarrier Interference in OFDM Systems: Unified Formulation and Analysis
Fernando Cruz-Roldán, Wallace A. Martins, Fausto García G. +2
A new unified formulation for seven different orthogonal frequency-division multiplexing (OFDM) systems is presented. The proposed formulation relies on six parameters and encompas…
Instantaneous PSD Estimation for Speech Enhancement based on Generalized Principal Components
Thomas Dietzen, Marc Moonen, Toon van Waterschoot
Power spectral density (PSD) estimates of various microphone signal components are essential to many speech enhancement procedures. As speech is highly non-nonstationary, performan…
Localization Uncertainty in Time-Amplitude Stereophonic Reproduction
Enzo De Sena, Zoran Cvetkovic, Huseyin Hacihabiboglu +2
This article studies the effects of inter-channel time and level differences in stereophonic reproduction on perceived localization uncertainty, which is defined as how difficult i…
