MSc. Thesis Title

Study of the interferences for planning broadcasting DRM 26 MHz  services for a period of sporadic ionospheric propagation 

 

MSc. Thesis Description

This project is focused on the description of the behaviour of the 26 MHz band for a local broadcast service of DRM signal in months when is possible the mechanism of sporadic ionospheric propagation.

A measurement campaign is carried out, monitoring for three months frequencies of this band. For this measurements, a complete system of reception is designed with the necessary equipment, including a DRM receptor and a spectrum analyzer, so that they can provide enough information to create a results database for this study.

With the analysis of this database, the study provides a methodology in the classification of the interferences detected in this band, just as the definition of the main characteristics and behaviours associate to each of them, with an particular analysis of the DRM signal received with this mechanism of propagation from remote transmitters in Europe.
