P_rec = 57 - ceil(3.6*log2(1+N))

P_max = 60 - ceil(3.6*log2(1+N))

Datarates in MBit/s:

Bandwith/Modulation	QPSK	16 QAM	32 QAM	64 QAM	256 QAM	1024 QAM
1,6 MHz (US) 1,28 MBaud	2,5	5	6,25	7,6	10	12,5
3,2 MHz (US) 2,56 MBaud	5,1 (minSNR 15 dB)	10,1 (minSNR 21 dB)	12,75 (minSNR 24 dB)	15,3 (minSNR 27 dB)	20,4 (minSNR 33 dB)	25,5
6,4 MHz (US) 5,12 MBaud	10,2	20,4	25,5	30,7	41	55
8 MHz (DS)	13,9 (minSNR 10 dB)	27,8 (minSNR 16 dB)	34,8 (minSNR 19 dB)	41,7 (minSNR 22 dB)	55,6 (minSNR 28 dB)	69,5

DSRate = Bandwidth/1,15 * lb(Symbole)

USRate = Bandwidth/1,25 * lb(Symbole)

1,15 and 1,25 are roll off factors resulting of the slope of the channel (in spectrum)

SNR = 10 x lg ( 2^(Datarate/Bandwidth) - 1)
