Field Trial on DTMB-A for the Coverage Performance of HDTV Program Under High Mobility and Spectrum Efficiency

The coverage performance for Digital Television/ Terrestrial Multimedia Broadcasting-Advance system and 3GPP “Further evolved Multimedia Broadcast Multicast Service”, long-term evolution-based broadcasting system defined by release 16 (R16) with different working parameters has been evaluated through the field trial in Shenzhen with a focus on high-speed mobility car with reasonably high spectrum efficiency. The trial uses the same transmitter facility of same the RF hardware, at the same frequency and with the same power. Results show that terrain is major deterministic factor for coverage performance for each system and well-designed longer time-interleaver for R16 is indispensable to users' satisfaction under this application scenario.
