Downlink Massive MU-MIMO with Successively-Regularized Zero Forcing Precoding [PDF]

IEEE Wireless Communications Letters, 2022
In this letter, we consider linear precoding for downlink massive multi-user (MU) multiple-input multiple-output (MIMO) systems. We propose the novel successively-regularized zero forcing (SRZF) precoding, which exploits successive null spaces of the ...

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
International audienceThis 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.

Fully Decentralized Approximate Zero-Forcing Precoding for Massive MIMO Systems

IEEE Wireless Communications Letters, 2019
We analyze the downlink of a massive multiuser multiple input, multiple output (MIMO) system where antenna units at the base station are connected in a daisy chain without a central processing unit and only possess local channel knowledge. For this setup,

Optimal Zero-Forcing precoding design : oversampled FB frame approach

2010 IEEE International Conference on Acoustics, Speech and Signal Processing, 2010
This paper presents a frame analysis of Zero Forcing (ZF) precoding problem. It shows that from a frame point of view, the filter bank (FB) channel is a synthesis frame and its canonical dual analysis frame is the optimal ZF precoder under total power ...

Minimum BER block precoders for zero-forcing equalization [PDF]

IEEE International Conference on Acoustics Speech and Signal Processing, 2002
In this paper we derive an analytic expression for the linear precoder which minimizes the bit error rate (BER) for block transmission systems with zero-forcing equalization and threshold detection. The design is developed for the two standard schemes for eliminating inter-block interference; viz, zero padding (ZP) and cyclic prefix (CP).

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 ...

Joint and distributed linear precoding for centralised and decentralised multicell processing [PDF]

, 2010
Linear precoding techniques are designed for both joint and distributed Multi-Cell Processing (MCP), where both centralised and decentralised Channel State Information (CSI) exchange scenarios are considered.
