I am doing a project on signal processing in which i have to find ifft of band pass signal(2-10 GHz). normal code is working for low pass signal only.
kindly suggest some modification
 

You can downcovert the signal to baseband by multiplied e^-j*f0(n) series. f0=fRf/fs.
 
Hi ashumtech,

you can treat your signal like a low-pass one (0 to 10 GHz).
Simply, that 20% of unused spectrum will be zero.
Regards
