CDM-710G High-Speed Satellite Modem Revision 1
Eb/No Measurement MN-CDM710G
B–2
Example: In the diagram that follows, the (Co+No)/No measured is 4.6 dB. If Rate 1/2 QPSK is
used, this corresponds to an Eb/No of approximately 2.8 dB (DVB-S2).
The relationship used to derive the table values is as follows (only simple way for DVB-S2):
Eb/No = 10 log
10
(10
(Co+No/No )/10)
-1) – 10 log
10
(Spectral Efficiency)
and:
• Eb/No and (Co+No)/No are expressed in dB;
• Spectral Efficiency includes the modulation type, code rate, overhead and framing
and is shown in Tables B-1 and B-2.
