I have computed power spectrum of a signal using Lomb-Scargle periodogram, I want to get the total power of the signal, Please help me in this regard

For as far as I know, if you have the power spectral density, the total energy of the signal is simply the integral of the power spectral density which ought to be the same as the integral of the signal squared. In case of a digital signal, simply the sum.
