fft of iq data matlab
How do you find the Fourier transform of a signal in Matlab?
Compute the Fourier transform of the signal, and create the vector f that corresponds to the signal's sampling in frequency space. y = fft(x); fs = 1/Ts; f = (0:length(y)-1)*fs/length(y);
What is Fftshift in Matlab?
Y = fftshift( X ) rearranges a Fourier transform X by shifting the zero-frequency component to the center of the array.
If X is a vector, then fftshift swaps the left and right halves of X .
If X is a matrix, then fftshift swaps the first quadrant of X with the third, and the second quadrant with the fourth.fs = 1000; t = 0:1/fs:1-1/fs; x = cos(2*pi*100*t) + randn(size(t)); Obtain the periodogram using fft .
The signal is real-valued and has even length.
Because the signal is real-valued, you only need power estimates for the positive or negative frequencies.
