- * As defined on EN 300 429 Annex A and on ITU-T J.83 annex A, the DVB-C
- * roll-off factor is 0.15.
- * According with the specs, the amount of the needed bandwith is given by:
- *	Bw = Symbol_rate * (1 + 0.15)
- * As such, the maximum symbol rate supported by 6 MHz is
- *	max_symbol_rate = 6 MHz / 1.15 = 5217391 Bauds
- *NOTE: For ITU-T J.83 Annex C, the roll-off factor is 0.13. So:
- *	max_symbol_rate = 6 MHz / 1.13 = 5309735 Baud
- *	That means that an adjustment is needed for Japan,
- *	but, as currently DRX-K is hardcoded to Annex A, let's stick
- *	with 0.15 roll-off factor.
