Trellis-Based Noise Modulation with Soft-Decision Viterbi Detection
Razieh Torkamani, Hadi Zayyani, Mohammad Salman +2
Noise modulation conveys information through the statistical properties of noise rather than conventional deterministic signal parameters. This paper investigates a trellis-based n…
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…
