Digital Radio Mondiale ( Drm ) : Mw Simulcast Tests in Mexico

This report presents the study on the performance and related propagation aspects of the DRM system in Simulcast configuration developed after an extensive measurement campaign in the coverage area of an experimental network installed in México City (México). The study analyzes the quality of analogue and digital services based on a set of static and mobile measurements done during the year 2006. This report contains information regarding, received audio quality statistics and minimum usable field strength thresholds. Also the potential interferences between analogue and digital signals are studied. Finally, the ITU-R recommendations that have been traditionally used to predict field strength values for both the analogue and the new digital service are evaluated.
