Optimization of the Receiving Orientation Angle for Zero-Forcing Precoding in VLC [PDF]
IEEE Communications Letters, 2021 We study the performance of linear zero-forcing (ZF) precoding in multiuser multiple-input single-output visible light communications (VLC) when we are able to select the receiving orientation angle (ROA) of each user. For radio-frequency communications, the non-line-of-sight rich scattering environment usually ensures the linear independence among ...

Zero-Forcing Precoding and Generalized Inverses [PDF]
IEEE Transactions on Signal Processing, 2008 We consider the problem of linear zero-forcing precoding design and discuss its relation to the theory of generalized inverses in linear algebra. Special attention is given to a specific generalized inverse known as the pseudo-inverse. We begin with the standard design under the assumption of a total power constraint and prove that precoders based on ...

Symbol-Level Precoding Through the Lens of Zero Forcing and Vector Perturbation [PDF]
IEEE Transactions on Signal Processing, 2022 Symbol-level precoding (SLP) has recently emerged as a new paradigm for physical-layer transmit precoding in multiuser multi-input-multi-output (MIMO) channels. It exploits the underlying symbol constellation structure, which the conventional paradigm of linear precoding does not, to enhance symbol-level performance such as symbol error probability ...

RIS-Aided Secure Communications With Regularized Zero-Forcing Precoding
IEEE Transactions on Information Forensics and SecurityReconfigurable intelligent surfaces (RISs) have been shown effective in strengthening the physical layer security of wireless systems, and the two-timescale design was proposed to tackle the challenges in channel estimation and phase-shift control. However, existing maximum ratio transmission (MRT) based precoding design is not efficient in mitigating ...

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).
