Disruptive digital pre-correction available for Vyper satellite modulator
Amsterdam, September 10, 2015 – TeamCast, the world-renowned leader in digital modulation technologies for Digital Terrestrial Television (DTT), Wireless Transmission and Satellite Applications, is introducing a new key feature for its successful Vyper satellite modulator at IBC 2015.
Digital pre-correction of the satellite’s signal chain is a technical challenge. First generation solutions have been available on the market for a few years. The benefits they bring are not as high as expected, especially for the low order constellations which are the most widely used: QPSK and 8PSK.
TeamCast is introducing a new and innovative digital pre-correction solution on its VYPER range of satellite modulators. This second generation technique offers significant gains in budget margin, from 1.5 dB for 8PSK to 5 dB for 32APSK. It is available as a simple software upgrade for the VYPER modulators.
“This second generation solution is very efficient and will be usable with widely used constellations such as QPSK and 8PSK, while previous techniques are only efficient with high order constellations (e.g. 16APSK and 32APSK), which makes them of limited interest. Again, we are bringing new opportunities to operators through the disruptive technologies available for our VYPER range» says Christophe Trolet, Business Unit Manager at TeamCast.
This new Vyper pre-correction solution will be demonstrated on TeamCast’s stand #2.B51.
