Hello,
I was going thru the implementation of ofdm_sync_sc_cfb_impl.cc. As it says,
it implements
[1] Schmidl, T.M. and Cox, D.C., "Robust frequency and timing
synchronization for OFDM", Communications, IEEE Transactions on, 1997.
with modified normalization.
However I was wondering that in industry, which method is used dominantly
Auto-correlation based or Cross-correlation based.
I went thru a couple of papers which states pros and cons of both the
methods, however it is not clear to me which method is dominant and why ?
