If the "heavy lifting" in your code is in the FFT operations, and the FFT operations are of reasonably large size, then just calling the cufft library routines as indicated should give you good speedup and approximately fully ...

Computing FFT and IFFT with FFTW library C++ - Stack Overflow

WebFFTW is a C subroutine library for computing the discrete Fourier transform (DFT) in one or more dimensions, of arbitrary input size, and of both real and complex data (as well as of even/odd data, i.e. the discrete cosine/sine transforms or DCT/DST). We believe that FFTW, which is free software, should become the FFT library of choice for most ...
