Service-Area Robust NOMA for Pinching Antennas Systems
Zoran Hadzi-Velkov, Slavche Pejoski, Jia Guo +2
Pinching-antenna systems (PASS) enable near-field beam focusing using radiating points along a dielectric waveguide, but coherent spherical-wave superposition makes their channels…
Spatially Robust Near-Field SWIPT Using Pinching Antennas: Rate-Energy Tradeoff Bounds
Zoran Hadzi-Velkov, Marija Poposka, Slavche Pejoski +1
Pinching Waveguide Antennas (PWAs) offer significant potential for simultaneous wireless information and power transfer (SWIPT) by enabling precise near-field energy focusing. Howe…
Leveraging Convolutional Sparse Autoencoders for Robust Movement Classification from Low-Density sEMG
Blagoj Hristov, Zoran Hadzi-Velkov, Katerina Hadzi-Velkova Saneva +2
Reliable control of myoelectric prostheses is often hindered by high inter-subject variability and the clinical impracticality of high-density sensor arrays. This study proposes a…
Gradient Descent Methods for Regularized Optimization
Filip Nikolovski, Irena Stojkovska, Katerina Hadzi-Velkova Saneva +1
Regularization is a widely recognized technique in mathematical optimization. It can be used to smooth out objective functions, refine the feasible solution set, or prevent overfit…
Convergence Rate Maximization for Split Learning-based Control of EMG Prosthetic Devices
Matea Marinova, Daniel Denkovski, Hristijan Gjoreski +2
Split Learning (SL) is a promising Distributed Learning approach in electromyography (EMG) based prosthetic control, due to its applicability within resource-constrained environmen…
