Digital Radio Mondiale (DRM) DIGITAL RADIO MONDIALE DRM MULTI-CHANNEL SIMULCAST, URBAN AND INDOOR RECEPTION IN THE MEDIUM WAVE BAND
ثبت نشده
چکیده
Firstly, an Introduction section describes the transmission and reception infrastructures. Subsequently, results will be summarized in three sections: Simulcast, Monocast DRM and Monocast DRM Indoor Reception. The first study analyzes the quality of analogue and digital services in the multi-channel simulcast based on a set of static and mobile measurements. Also the potential interference between the analog and digital signals is studied providing different power ratios between them. In the second study the performance of an operational DRM broadcasting station in order to cover a city as Madrid can be assessed. Finally, the indoor reception of the mentioned DRM broadcasting service was studied. This report contains information regarding, received audio quality statistics and minimum usable field strength thresholds. Radiocommunication Study Groups

متن کاملUrban Radio Propagation Measurement for Digital TV Broadcast in Jakarta, Indonesia
Radio propagation measurement is carried out in Jakarta, Indonesia, in anticipation of digital TV implementation in the country. Measurements are made using a fixed, portable receiver outdoors and indoors. Spatial variations of the received power, both large-scale and small-scale, are measured in these locations. Results show that the largescale path loss variation characteristics, as described...
