In my opinion/experience at least two-fold over-sampling is to be recommended
with OFDM, The standard 802.11n has a mode with 40MHz bandwidth (not to mention
802.11ac). I have the feeling the dynamic range of 48dB is somewhat small for
OFDM. Especially without fast AGC.

Not to disparage some fine work, but in the specific example cited, the
existing, standard, 50Msps mode (8-bit samples) should also work, unless 48dB
of dynamic range isn't adequate.

Hi Lists,
I have tried Marc Epards 100Msps hack from https://github.com/mepard/N210CeVI
on XCVR2450. It's extremely cool. I verified that the 36MHz bandwidth option on
the XCVR2450 actually works (and it does). With this kind of bandwidth it is
possible to investigate true 802.11n and LTE signals (I wish we had this
feature for TX as well).
Many thanks Marc!
