Improved Massive MIMO RZF Precoding Algorithm Based on Truncated Kapteyn Series Expansion
Information, 2019 In order to reduce the computational complexity of the inverse matrix in the regularized zero-forcing (RZF) precoding algorithm, this paper expands and approximates the inverse matrix based on the truncated Kapteyn series expansion and the corresponding ...

Spectrally Precoded OFDM [PDF]
IEEE Transactions on Communications, 2006 By bilinearly transforming the rectangularly pulsed multicarrier basis signals, new basis sets containing full-response continuous basis signals are developed for constructing spectrally efficient orthogonal frequency-division multiplexing (OFDM) signals with or without cyclic prefix (CP) or zero padding (ZP).

Journal of the Royal Society of New Zealand, Volume 56, Issue 4, August 2026.Accurate environmental and climate modelling depends on the availability of large observational datasets, yet the generation of such data is often costly and logistically challenging for individual research groups. This limitation is particularly acute in New Zealand, where geographic isolation, complex topography, and strong climatic gradients require

An Optimal Edge Data Caching Scheme Based on Improved Particle Swarm Optimization
Concurrency and Computation: Practice and Experience, Volume 38, Issue 13, July 2026.ABSTRACT Mobile Edge Computing (MEC) alleviates the performance bottlenecks of traditional cloud computing in latency‐sensitive scenarios by moving computational resources to network edge nodes. In recent years, numerous research efforts have focused on developing edge data caching (EDC) strategies that enable app vendors to enhance caching performance

Rethinking Emotional Labor: AI's Role in Shaping Consumer and Worker Well‐Being
Journal of Consumer Affairs, Volume 60, Issue 2, Summer 2026.ABSTRACT This article offers a commentary on the role of AI‐driven systems in emotional labor and its implications for consumers' well‐being. The central insight is that AI systems can alleviate service providers' emotional burden while providing consistent support, which challenges the notion that only humans can deliver authentic emotional support ...

A Performance‐Based Earthquake Fatality Modeling Framework Using Collapse Volume Ratios
Earthquake Spectra, Volume 42, Issue 2, May 2026.Conventional earthquake fatality models are commonly implemented using a binary representation of building collapse, an assumption that overlooks severe failure modes and systematically underestimates fatalities. To address this limitation, this study advances the collapse volume ratio—a continuous metric quantifying the reduction of survivable space ...

Costa Precoding in One Dimension [PDF]
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006 We design an optimum modulator for the Costa (dirty-paper) precoding problem under the constraint of a binary signaling alphabet, and assuming the interference symbols belong to a binary constellation. We evaluate the performance of our technique in terms of the mutual information between the channel input and output, and compare it to that of ...

Earthquake Spectra, Volume 42, Issue 2, May 2026.This article aims at exploring and validating the use of 3D physics‐based simulated ground motions as seismic input for the derivation of seismic fragility curves based on nonlinear dynamic numerical analyses. Fragility curves are computed for a set of pre‐code (i.e., designed only for vertical loads), reinforced concrete building types representative ...

Linear Precoded Index Modulation [PDF]
IEEE Transactions on Communications, 2019 Index modulation (IM) is an attractive concept for next generation communication systems. However, as an emerging technique, there are still some challenges need to be tackled in this frontier. In this paper, we consider two aspects of IM, which are diversity and detection complexity.
