Abstract

The present article shows the design and test of a unified-processing device for detection and demodulation of narrow and broadband communication signals, as well as navigation signals from GLONASS and GPS systems. The specific processing for each type of signal is described within the general framework of the proposed device. Performance indicators, such as symbol error probability (SEP) and energy losses, were computed using simulations of the device and the corresponding results are presented for discussion.

Keywords: satellite communications, satellite navigation, architecture, integration.

 

Resumen

En este artículo se muestran los resultados concernientes al diseño de un dispositivo de procesamiento unificado que permite detectar y demodular tanto señales de comunicación de banda angosta y banda ancha, como señales de navegación de los sistemas GLONASS y GPS. Se esclarece la especificidad de procesamiento para cada tipo de señal enmarcado en la estructura general del dispositivo. Los valores de probabilidad de error de símbolo y las pérdidas energéticas del sistema, obtenidos en un simulador del dispositivo, son presentados.
