Optimal Training in large TDD multi-user downlink systems under zero-forcing and regularized zero-forcing precoding [PDF]
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010 This paper considers a large multi-user time-division duplex (TDD) system, where the base station (BS) acquires channel state information via pilot signaling from the users. In the downlink the BS employs zero-forcing (ZF) and regularized zero-forcing (RZF) precoding.

Impact of Channel Aging on Zero-Forcing Precoding in Cell-Free Massive MIMO Systems [PDF]
IEEE Communications Letters, 2021 In the context of cell-free massive multi-input multi-output (mMIMO), zero-forcing precoding (ZFP) requires the exchange of instantaneous channel state information and precoded data symbols via a fronthaul network.

Asymptotic Behavior of Zero-Forcing Precoding based on Imperfect Channel Knowledge for Massive MISO FDD Systems [PDF]
ICC 2023 - IEEE International Conference on Communications, 2023 In this work, we study the asymptotic behavior of the zero-forcing precoder based on the least squares (LS) and the linear minimum mean-square error (LMMSE) channel estimates for the downlink (DL) of a frequency-division-duplex (FDD) massive multiple ...

Optimal User Loading in Massive MIMO Systems with Regularized Zero Forcing Precoding [PDF]
IEEE Wireless Communications Letters, 2016 We consider a downlink massive multiple-input multiple output system employing regularized zero-forcing precoding. We derive the asymptotic signal-to-leakage-plus-noise ratio (SLNR) as both the number of antennas and the number of users go to infinity at

C-RAN Zero-Forcing With Imperfect CSI: Analysis and Precode & Quantize Feedback [PDF]
IEEE Transactions on Wireless Communications, 2022 Downlink joint transmission by a cluster of remote radio heads (RRHs) is an essential technique for enhancing throughput in future cellular networks. This method requires global channel state information (CSI) at the processing unit that designs the joint precoder. To this end, a large amount of CSI must be shared between the RRHs and that unit.

Low-Resolution Precoding for Multi-Antenna Downlink Channels and OFDM [PDF]
Entropy, 2022 Downlink precoding is considered for multi-path multi-input single-output channels where the base station uses orthogonal frequency-division multiplexing and low-resolution signaling.

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.

Zero-Forcing Precoding With Partial CSI in Multibeam High Throughput Satellite Systems
IEEE Transactions on Vehicular Technology, 2021 Precoding has emerged as a prominent technique to mitigate interbeam interference (IBI) in the forward link of a multibeam high throughput satellite system. In this paper, we consider zero-forcing (ZF) precoding to mitigate IBI.
