How to calculate energy spectral density (ESD) of a signal?

I would like to calculate the energy spectral density (esd) of a signal sampled at 57000 Hz.

I use the attached code to calculate psd and frequency values.

Does anyone know how to relate the psd to esd?

According to wikipedia, the esd is the product of discrete-time Fourier transform and complex conjugate.

Are the esd and average power related?
