How can I do zero padding before IFFT? (matlab)
显示 更早的评论
I have an issue of applying IFFT in matlab.
I have signal in frequency domain (X(k)) with bandwidth (2−3)MHz. with with seperation freqency is 10khz and 101 point. So, in order to apply IFFT, i just wrote:
Xf= IFFT(X);
plot(0:(1/1e6):Nf*(1/1e6),Xf)
Then, i got symmetric figure.
I want to pad zeros before IFFT. can you help me?
