Annex B

 

DVB-S Phase noise tolerance

 

SSB phase-noise power spectral density < -68 
– 10*log(Rs/20) dBc/Hz at 

δF = 10 kHz offset 

Phase noise power spectral density of the form 
C – 20*Log(

δF) 

δF = Frequency offset from carrier 
Rs = Symbol-rate (Msymbol/s)

See Table B.14

 

Table B.12 shows the Eb/No requirements for DVB-S and Table B.13 for DVB-S2 
Es/No requirements to ensure error-free demodulation for all supported FEC rates.

 These specifications apply in the presence of thermal noise at the threshold Eb/N

0 

ratio given in Table B.12

 These specifications apply in the presence of thermal noise at the threshold Es/No ratio given in Table B.13 and assume a degradation to 

the thermal noise performance of 0.3 dB.
