Abstract :
The digital era triggers new and ambitious services running on different platforms. Digital mobile systems provide a constrained quality communications, thereby, an acceptable quality is only ensured when the signal-to-noise ratio is above a certain limit and, even though, usually at a lower capacity than fixed systems. In this paper, we report a DVB-T measurement campaign at 730 MHz with an EIRP (effective isotropic radiated power) up to 100 W. As far as we know, this is the first publication describing radio-frequency (RF) measurements as well as mobile HDTV subjective results at a high speed around 140 km/h. By mobile subjective (MS) results, it is meant, block, slice or frame losses resulting in visual artifacts. The correlation between MS measurements and RF measurements like receiving power, carrier-to-noise-ratio and modulation error rate is discussed in the paper. The paper ends by providing some recommendations namely, the minimum transmitting power and packet error rate (PER) to achieve visual artifact-free condition.
