Satellite Uplink and Downlink Simulation is a communication system model developed using MATLAB Simulink. This project simulates the uplink (ground to satellite) and downlink (satellite to ground) ...
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 ...
This project focuses on the design, simulation, and performance optimization of two key digital modulation techniques — Quadrature Phase Shift Keying (QPSK) and Offset Quadrature Phase Shift Keying ...
Four-dimensional QPSK modulation transmission scheme based on entropy-coding-aided symbol selection.
We propose a four-dimensional quadrature phase shift keying (4D-SS-QPSK) modulation transmission scheme based on entropy-coding-aided symbol selection. The proposed scheme integrates Huffman coding ...
Abstract: In the rapidly evolving landscape of modern communication systems, the demand for high-speed, reliable, and efficient data transmission has never been greater. This paper compares ...
