Completed project

Vortex waves: possible applications for radio communications?

In recent years, the research community have shown interest in the study of some “non-conventional” properties of electromagnetic radiation in order to evaluate its possible application in the field of applied sciences.

Long term perspectives of DTT Convergence towards 5G: Applications of 3GPP Rel-14 to Italian scenarios

3GPP has defined in Release 14 the new eMBMS system, whose characteristics are well aligned to the technical requirements coming from the broadcast sector for TV services.

DVB-S2X - the DVB-S2 extension for the future of satellite communications

First 4k HEVC satellite transmission using DVB-S2X from Turin

Born as an extension of second generation satellite broadcast standard DVB-S2, the DVB-S2X offers new configurations that provide improved performance in S2 scenarios (DTH, broadband and interactivity, DSNG, and professional applications, contribution and distribution TV), and extends the operating modes to cover new emerging segments such as mobile reception (airplanes, trains, ships, etc.). The new system, based on the excellent technologies of DVB-S2, introduces innovative elements at the modulation, resulting in a more extensive and granular operating range in terms of  signal-to-noise ratio, as well as an increased spectral efficiency thanks to new modulation schemes and spectrum roll-off values. With the DVB-S2X the “channel bonding” is now introduced: 2 or 3 transponder can be used simultaneously, in order to transmit very high capacity streams, enabling the broadcast of UHD bouquets.

The first satellite transmission of a HEVC encoded UHD-4k bouquet, using the new broadcasting standard DVB-S2X, has been carried out on 2014 at the Centre for Research and Technological Innovation Rai in Turin.

Active project

SFN Scope: an innovative analysis system for DVB-T SFN signals

Created and patented by Rai-CRIT, SFN-Scope can analyze SFN DVB-T signal received in the service area, and identify the individual components of the signals emitted from transmitters in service to the area, with their levels and delays. SFN-Scope thus makes now possible to simplify the signal quality control operated by RaiWay teams, and get actual feedback for level/delay measurment that until now were only available in a “aggregate” form by ordinary instruments.

Active project

Laboratory characterization of the antenna performance for a typical LTE-800 device

The characterisation of a typical LTE cellphone embedded antenna has been done, in order to enable the simulations of geographic coverage for a terrestrial television service towards mobile terminals.
