Melcom supply Newtec's Equalink Technology

Equalink is a revolutionary linear and non-linear pre-distortion technology implemented in Newtec DVB-S and DVB-S2 modulators, designed to compensate for the effects of imperfections in the filters and amplifiers of the satellite. This pre-correction improves the performance of the end-to-end satellite communication channel by a typical 2 dB and allows the use of higher modulation schemes such as DVB-S2 16APSK or 32APSK on carriers occupying a full transponder.

For Direct-to-Home broadcasting applications, Internet backbones and other high speed satellite applications, this performance improvement represents up to an additional 11 % of data traffic in the same satellite capacity.

Equalink is a set of advanced digital filters and algorithms implemented in the modulator. The linear filter compensates for group delay and frequency response imperfections of the satellite input multiplexer (IMUX), while the non-linear pre-correction compensates for the combined effect of matched filters and transponder TWTA nonlinearities (AM/AM and AM/PM conversions).

Equalink can be used in conjunction with any standard satellite receiver and is very easy to operate.
