Fluid Antenna-Aided Noise Modulation: Spatial Diversity for Variance-Based Wireless Communication
Hadi Zayyani, Felipe A. P. de Figueiredo, Pedro M. R. Pereira +2
Noise modulation (NoiseMod) encodes information in the \emph{variance} of a transmitted noise-like waveform rather than in its amplitude, phase, or frequency, and is attractive for…
Performance Limits of FRIS Systems in Nakagami- Fading
Masoud Khazaee, Felipe A. P. de Figueiredo, Rausley A. A. de Souza +4
Fluid reconfigurable intelligent surfaces (FRIS) have recently emerged as a promising technology for enhancing wireless link reliability through spatial decorrelation. However, the…
Fast-TurboQuant: A Multiplier-Free Online Vector Quantization Approach
Pedro M. R. Pereira, Felipe A. P. de Figueiredo, Rausley A. A. de Souza
As large language models scale, memory bandwidth for key-value caches and retrieval-augmented generation systems becomes a critical bottleneck. While 1-bit quantization addresses t…
On the Practical Performance of Noise Modulation for Ultra-Low-Power IoT: Limitations, Capacity, and Energy Trade-offs
Felipe A. P. de Figueiredo, Pedro M. R. Pereira, Evandro C. Vilas Boas +3
Ultra-low-power (ULP) Internet of Things (IoT) applications demand communication architectures with minimal energy consumption. Noise Modulation (NoiseMod) addresses this by encodi…
Exact Statistical Characterization and Performance Analysis of Fluid Reconfigurable Intelligent Surfaces
Masoud Khazaee, Felipe A. P. de Figueiredo, Rausley A. A. de Souza +4
Fluid reconfigurable intelligent surfaces (FRIS) extend conventional RIS architectures by enabling physical reconfiguration of element positions, thereby introducing a fundamentall…
Optimal Bit Detection in Thermal Noise Communication Systems Under Rician Fading
Mohamed El Jbari, Fernando D. A. GarcÃa, Hugerles S. Silva +2
Thermal noise communication (TNC) enables ultra-low-power wireless links for Internet of Things (IoT) devices by modulating the variance of thermal noise, rather than using active…
