Hello,
I'm trying to make an FFT block in my hierarchical block, but I cannot seem to
find the correct syntax.
I'm trying to make it with a BLACKMAN_HARRIS windowing function, and it's easy
in a python program:
fft_forward = fft.fft_vfc(window_size, True,
(fft.blackmanharris(window_size)), 1)
fft_backward = fft.fft_vcc(window_size, False,
(fft.blackmanharris(window_size)), False, 1)
But in a c++ program it gets hairy. Does anyone have any experience with this?
gr::fft::fft_vfc::sptr fft_forward = gr::fft::fft_vfc::make(SIZE, true,
gr::filter::firdes::WIN_BLACKMAN_HARRIS, num_threads);
gr::fft::fft:vcc::sptr fft_reverse = gr::fft::fft_vcc::make(SIZE, false,
gr::filter::firdes::WIN_BLACKMAN_HARRIS, false, num_threads);
I believe what I have wrong is the Windowing, which is of the form:
const std::vector< float > & window
