SHAPING THE FUTURE SATELLITE OF COMMUNICATIONS 

 

ACM 

In Adaptive Coding and Modulation mode, the modulation parameters of the 
Baseband frames can vary over time, according to the instantaneous receiving 
conditions of the site where the frame will be received. In ACM there is a feedback 
mechanism between the demodulator and the modulator. This feedback 
mechanism dynamically tells the modulator which modulation parameters to use 
for each baseband frame. ACM allows operating satellite links with almost no 
margin, since the system adapts automatically to fading or interference conditions.

Newtec’s implementation of ACM for applications is called FlexACM. It relies on an 
unique very accurate linear and non-linear distortion measurement technology in 
the demodulator (called NoDE) and advanced traffic shaping technologies in the 
hub.

What are Pilots 

Pilots are unmodulated symbols grouped in blocks that can be added on the 
physical layer framing level.
