Field Measurements of a Hybrid DVB-SH Single Frequency Network with an Inclined Satellite Orbit
01 December 2010
Field measurements of a DVB-SH network with both satellite and terrestrial transmitters are presented. The system is a Single Frequency Network transmitting video streams to vehicular terminals with multiple antennas with up to 4 branches of receiver diversity. The signal is transmitted in the S-band at 2.1895GHz with both time and frequency synchronization of the terrestrial repeaters with the satellite's signal. The field measurements include data taken with multiple repeaters located in multiple cities and morphologies, as well as with various elevation angles to the satellite. This paper presents coverage data for these various morphologies, modulation and code rates as well as various MPE-iFEC interleaver settings used to ameliorate the effects of long shadows such as underpasses.
