This repository collects MATLAB coursework and group project artifacts for Truyen thong so / Digital Communications at the Faculty of Electronics and Telecommunications, VNUHCM - University of Science ...

BPSK is a simple and robust digital modulation technique widely used in communication systems, including satellite communication. MATLAB is used as a simulation tool to study how noise affects the ...

Abstract: Transmitting high capacity under low SNR conditions is increasingly a challenge in many wireless and free-space communications applications. E.g. in free space optical satellite links ...

Information is carried by changing the phase of the carrier. ->BPSK (Binary PSK): Uses two phases (0° and 180°). Very robust, but only 1 bit per symbol. ->QPSK (Quadrature PSK): Uses four phases (0°, ...

Abstract: Digital overlays in composite baseband systems provide a means to integrate new services while maintaining compatibility with existing structures. This paper presents a comparative study of ...
