@Ron Economos: Thanks for your reply.I've looked about the code.I think that maybe I'll implement it in the future,but not now: is too specific to a single application

@Marcus Müller:I've looked about correlate_and_sync method(are you speaking about it,isn't it?)Ye it can take good advantage from CUDA..
Ye,I've a FIR implementatio and I'm looking also for an FFT(with device code,so unlucky without cuFFT library).
here the problem is not only data outgoing from the block,but relative tags.also because for the moment I'm not supporting tags on the flow above CUDA.If u have good idea about how manage them,feel free to speak.

While I was reading the code,a question arise about this code( method work in cc implementation):

while(i < noutput_items) {
        if((corr_mag[i] - corr_mag[i-d_sps]) > d_thresh) {
          while(corr_mag[i] < corr_mag[i+1])

is not possible that the variable i will go outside the array corr_mag?I know that is necessary a strange pattern in order to have the last item greater than the previous..
