Yes, you can. Look into the gr-fft module documentation in the doxygen
docs.
Alternatively, you can simply link against FFTW [1] yourself and use
the FFT algorithms; gr-fft is a wrapper for that functionality
offering simplification and ease of use. But if an FFT is all that
you're after, going directly for FFTW might be the best choice; if you
need something non-standard such as 2D-FFT (or higher dimensions),
real-only transforms, sliced/strided, hundreds of transforms at
once... use FFTW. If you just want an N-Point FFT and are linking
against GR anyway, use gr-fft.
