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 signal in time domain,and remove it from the received signal.For example,y=x1+x2,and I want to remove x2 from the baseband recevied signal.
Now my idea is no only used the SCA algorithm mentioned in the new ofdm example, but also use other similar finer carrier frequency estimation algorithm.I want to combined the algorithms.So I ask the question in the maillist.
Thank you so much.
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 probably not much
that's better than S&C in a real world OFDM receiver, but I must
admit that I haven't implemented many OFDM synchronizers myself.
However, you say
> Now in my application,maybe this algorithm isn't enough.
which means that you have a mathematical measure that's not OK for
S&C, I guess. So in what way doesn't S&C suffice? What is it
about your application that makes S&C insufficient or impossible
to use?
Best regards,
Marcus

Dear all:
Thank you in advance.
1.
I want to ask a question about the new
ofdm example.And I know the receiver have used the
SCA(schmidl and cox algorithm) algorithm.Now in my
application,maybe this algorithm isn't enough.And I want to
ask whether have other good frequency offset correction
algorithm which have been implemented.
2.What is the algorithm used by the old
version of the ofdm example?Thanks.
Best regards,
zs
