Description

The software_imbe_decoder is using home-rolled FFT/IFFT functions which are much better left to a proper DFT library. Replace these functions with those of libfftw3 - the library can use SIMD instructions to compute the DFT much more efficiently than this code and it simplifies the decoder.
