ABE has now implemented in its digital modulators, in addition to the existing DVB-S and DVB-DSNG standards, the DVB-S2 standard.
The new modulator (which covers all 3 standards), can have IF outputs at 70MHz and L-BAND. Moreover, the solution can also include up to 4 MPEG encoders and multiplexer.
The modulation schemes supported for the DVB-S2 are: QPSK, 8PSK, 16APSK and 32APSK. Error-correction codes implemented with LDPC (Low Density Parity Check), are much more efficient than the convolutional codes employed in the DVB-S standard (by approximately 2dB) and really close to the theoretical Shannon limit.
In comparison with the DVB-S standard, for the same bandwidth and the same signal level, the DVB-S2 standard can support an increase in transmission capacity (BIT-RATE) greater than 30%.
The DVB-S2 modulator is mainly employed in Satellite Uplinks and terrestrial Microwave Links.
Furthermore, ABE has also developed a DVB-S / S2 receiver board that can be included in the digital and / or analogue transmitters or provided in a stand-alone unit.
Last but by no means least, the average price of the DVB-S2 modulator is similar to the DVB-S / DSNG modulator, even when market prices are normally much higher.
