Sistema modulador y demodulador de la estación Terrena Cubesat – ud para la comunicación con la red Satnet

Abstract

The degree work developed has the design of a modulation and demodulation scheme that allows the integration of the Cubesat-UD earth station with other international earth stations, therefore obtained a modulation and demodulation scheme suitable for the Cubesat-UD earth station, which allows the earth station to take a signal by means of an electromagnetic wave that travels with a specific frequency, according to international standards, and mount the information either for the transmission or reception process, on the other hand, the design of the modulation and demodulation systems using FSK were designed from VHDL hardware description language, which allows easy hardware construction with the specific design schemes of both the modulator and the modulator needed by the earth station, and highlights the results and tests developed to the physical schemes of FSK Modulation and Demodulation at different brand and space frequencies and the process of transmission and reception of signals using instrumentation and measurement equipment to analyze the electromagnetic spectrum of FM signals used and bandwidth.
