Subset Regularized Zero-Forcing Precoders for Cell-Free C-RANs [PDF]
2021 29th European Signal Processing Conference (EUSIPCO), 2021 This paper formulates regularized zero-forcing (RZF) precoders that are both network- and user-centric for the downlink of centralized radio-access networks operating in a cell-free fashion. The transmission to every user involves a distinct subset of access points (APs), and every AP participates in the transmission to a distinct subset of users ...

Low‐complexity unsupervised learning‐based hybrid precoding for massive MIMO systems
IET Communications, 2023 Hybrid precoding can significantly reduce the number of required radio frequency (RF) chains in massive MIMO systems. However, due to the large number of antennas and the high‐dimensional channel, the existing hybrid precoding algorithms usually require ...

A combinatorial precoding scheme of cell‐free massive MIMO with channel aging
IET Communications, 2022 Here, we investigate the precoding schemes for the downlink data transmission of a time‐division duplex cell‐free massive multiple‐input multiple‐output (MIMO) system with channel aging, which arises from the user mobility.

Hybrid precoding based on matrix-adaptive method for multiuser large-scale antenna arrays. [PDF]
PLoS ONE, 2017 Massive multiple-input multiple-output (MIMO) is envisioned to offer a considerable improvement in capacity, but it has a high cost and the radio frequency (RF) chain components have a high power consumption at high frequency.

Multicellular Zero Forcing Precoding Performance in Rayleigh and Shadow Fading [PDF]
2011 IEEE 73rd Vehicular Technology Conference (VTC Spring), 2011 In this paper we propose an analytical evaluation of the performance of the zero forcing precoding technique in terms of outage probability in a multicellular multiuser context. The channel model includes path loss shadowing and Rayleigh flat fading. Two cases are examined. The first one considers a constant lognormal shadowing.
