Adaptive Coding and Modulation (ACM)

Optimizes performance to the

available capacity

rather than worst-case scenario.

Significant increase in

capacity/availability

Forward link DVB-S2.

ACM, VCM

Return link modulation CPM,

QPSK, 8PSK and 16QAM

Per-timeslot ACM configuration

more granular and flexible just-in-

time timeslot adaptation.

(16)

Continuous Phase Modulation (CPM)

4-state modulation

Innovative weighted average pulse

shape

CPM may give lower-cost terminals

Non-linear signals > cheaper

amplifiers

Terminals support both

modulations

ODU instabilities make CPM relatively

better

Coding / Carrier / Access

16-state turbo

code

for QPSK, 8PSK and 16QAM

benefits substantially from last decade coding development

Random Access option for SCADA / intermittent data

more responsive - less delay

DVB-S2 Continuous Carrier return link

(planned)

option in adaptive or variable mode (ACM/VCM)

From RCS+M

DVB-S2 adapted to low rates.

Power headroom reporting. EIRP control alternative

Constant power spectrum density for carriers of different BW

Constant EIRP

Generic Stream Encapsulation (GSE)

Generic Stream

Encapsulation (GSE) with

strengthened integrity

control in forward link.

Return link packet

encapsulation (RLE) is

adaptation of GSE.
