But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...

This repository implements an OFDM (Orthogonal Frequency Division Multiplexing) communication system in MATLAB. It represents a simplified version of the WiFi (802.11) PHY layer, including packet ...

Abstract: Higher-order optical multilevel signaling is a key technique for future ultra-high speed signal transmission at 100 Gbit/s or beyond. In this paper, we review various multilevel transmitter ...

The receiver (RX) with an adaptive demodulator design and load-optimized single-ended to differential converting active balun supports the high-speed noncoherent demodulation. The proposed sub-THz ...
