It's a very similar implementation to the 'new' versions. In stock GNU

Dear Marcus Müller:
Actually my problem is:
y=useful information+x*h(channel)*cfo(carrier offset due to
the local oscillator between the interference and the radar)+noise.
I want to turn y to
new_y=useful information+noise.
So I need know the channel(h) a

Hi zs,
this reminds me very much of OFDM radar technologies, as your problem
boils down to finding a good estimator for the spectral properties of
your OFDM frame as well as the time it reached you.
I think you should have a look at chapter 3, "OFDM Radar Algorithms" of
[1]; you might find that co
Dear Marcus Müller:
Do you know which is the synchronization algorithm used in the old version of
ofdm example?Where is the source code of the old ofdm version in
gnuradio?Thanks.
Any other suggestions?
Thank you.

Dear Marcus Müller:
Thank you so much for your kindly reply.
The SCA is adequate for a correct demodulation of the signal while maybe
inadequate for estimate the precise frequency shift.I don't have the
synchroniztion device.In my application,I need to reconstruct one transmit

Dear zs,
basically, Schmidl and Cox is a very good algorithm, because it can
achieve the same quality of synchronization with half of the
synchronization overhead compared to other approaches, or a better
performance with the same amount.
I must admit that from the top of my head, there's probabl
