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…
A Double Proportionate Sparse Adaptive Filter for Impulsive Noise Environments
Mohammad Salman, Falah Ibrahim Al Hassan, Hadi Zayyani +2
Sparse adaptive filters and impulsive noise robust algorithms have largely been developed along separate tracks, leaving a gap when both properties are needed simultaneously. This…
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…
