I have N number of time-domain complex signals. And I want to find the corresponding power spectral density of these signals. The usual way I think is to find the autocorrelation of the signals. Then, the fourier transform of it. My question is, how do I find the power spectral density oof complex signals? Is it the same way? Autocorrelation of complex signals? Autocorrelation of the magnitude of the complex signals?
