After applying the inverse Fourier transform to real-valued signal I have got , as expected, complex numbers. But, I would like only the real part of the result to form the signal. Could someone give some help in this matter? Many thanks, Massilon.

Just taking the real part of your transformed data eliminates half of it. I would use the abs function instead (that uses the real and imaginary parts of your transformed data), if you want only real results.
