The paper deals with the problem of train arrival detection in tracks maintenance sites. Worker safety has, in fact, to be guaranteed and injuries due to undetected train transits are, unfortunately, very common. Several solutions have already been presented based either on human sentinels or automatic detection systems. They, however, suffer from high operating costs and long assembly time, respectively...
Performance assessment and large-scale monitoring of terrestrial digital video broadcasting (DVB-T) transmission apparatuses are currently a pressing need due to the rapid growth of related broadcasting networks in many countries. Power measurements, in particular, play a very important role since RF and IF signal power, RF channel power, RF and IF power spectrum, noise (or unwanted) power, and power...
The first results related to a wider research program, aimed at the realization of a DSP-based meter, mainly devoted to performance assessment and large scale monitoring of DVB-T systems and apparatuses, are presented. Satisfying repeatability, reduced measurement time (fast measurement rate) and cost effectiveness are, in particular, pursued. The paper mainly focuses on the digital signal processing...
