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
