We know that modulation in general can get complicated, and the various types phase modulated schemes can pack in more information than was once thought possible.
I tried to unpick a couple.
4D 2/3 TCM 8PSK DVB RS 500MBit/sec (Trellis Coded Modulation 8-phase Phase Shift Keying + Reed-Solomon correction).
and another..
1/2-rate QPSK Convolutional Encoding k=7 to 100MBit/sec.
Are there any handy ways to estimate the bandwidths needed for these common data modulations?
