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, ...

This repository contains a portfolio snapshot of a MATLAB-based software-defined radio receiver project for QPSK digital communication signal recovery. The project focused on building a complete ...

Abstract: In the field of modern mobile communication, (Quadrature Phase Shift Keying) QPSK modulation technology is widely used, which has a great advantage that it can work normally in a limited ...

The modulators are the basic requirement of the communication systems they are designed to reduce the channel distortion & to use in RF communication hence many type of carrier modulation techniques ...
