Abstract: In order for communication to be implemented efficiently in terms of power, bandwidth, and distance, information signal to be sent should be converted into various forms before it is ...

This project presents a complete end-to-end implementation of Quadrature Phase Shift Keying (QPSK) — a digital modulation technique used in real-world communication systems such as satellite, Wi-Fi, ...

Abstract: Ultrasonic index modulation can effectively improve the spectral efficiency and energy efficiency of intra-body communication systems. This letter proposes a codeword-based auto-correlation ...
