Question If we measure Eb/no at VSAT's end.and if i check the same at Hub end what will be the difference? or there should not be?
Answer hi,
it will all depend on how you design your link. you normally design to be some dB above threshold. for example, if the threshold for 10E-6 BER is 6 dB, you might be at 10 dB eB/no and if you use the same modualtion and coding for the inbound link, and you use the same margin, you would have the same value at the hub.
so it depends on
- modulation
- coding
- link availability objective
- system margin
