This project presents a MATLAB-based simulation of an 8-Pulse Amplitude Modulation (8-PAM) communication system using Sigma-Delta modulation and demodulation techniques. The system is modeled ...

Abstract: Wireless Power and Data Transfer (WPDT) circuits offers many advantages in the health domain and is a game changer in improving the health of mankind. This work proposed a clock recovery ...

Abstract: In this contribution, we explore the possibilities offered by various Space-Time (ST) modulation matrices when applied to space-time modulated metasurfaces. We focus on the simplest coding ...
