Hi, I'm trying to write a block that would compute FFT on the received samples, but I'm having trouble with finding how to perform FFT shift after the computation. Any help with that? So far I'm using
d_fft = std::make_unique<fft::fft_complex_fwd>(d_fftsize); memcpy(d_fft->get_inbuf(), d_fft_processed.data(), d_fftsize*sizeof(gr_complex)); //get samples from input and store them in input buffer d_fft->execute(); // compute the fft memcpy(d_fft_processed.data(), d_fft->get_outbuf(), d_fftsize*sizeof(gr_complex)); //get processed samples from output buffer and storing them in d_fft_processed I'll appreciate any help Bartek
