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 E.s 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!
