SkyEdge II DVB-S2 ACM Enhancements

Not all DVB-S2 implementations are equal .Gilat’s SkyEdge II is

more efficient than usual competing DVB-S2 ACM schemes. This

is due to the incorporation of the following enhancements :

Support of a wide range of ModCods including 16APSK and

32APSK with predistortion where required

Support for short and normal MPEG transport frames

Efficient packing and Concatenation

Advanced scheduling

Network-wide Frame optimization

SkyEdge II –Inbound Adaptivity

1. Adaptive Uplink Power Control

2. Adaptive channel selection

3. Adaptive ModCod allocation

AUPC (Adaptive Uplink Power Control)

Power Loop

Keep hub Rx at a nominal value

Keep BUC Tx in the linear zone

Compensate for:

Rain fade

Static attenuation (such as cable)

Satellite location offset and aging

Temperature, frequency effect on BUC gain
