Generate a time series from power spectral density
I have a force PSD of 2X2X63 acting at 2 points of 63 frequencies defined. For each frequency, there is a 2×2 matrix representing the auto and cross variances of the force. I want to construct a time signal of 2xN size where N is the size of the time signal. How do I do it?I have a force PSD of 2X2X63 acting at 2 points of 63 frequencies defined.
