How do you get power from power spectral density?

26.5.

A signal consisting of many similar subcarriers will have a constant power spectral density (PSD) over its bandwidth and the total signal power can then be found as P = PSD · BW.

What is spectral density function of a time series?

The spectral density is a frequency domain representation of a time series that is directly related to the autocovariance time domain representation. In essence the spectral density and the autocovariance function contain the same information, but express it in different ways.

How do you interpret power spectral density?

Power spectral density function (PSD) shows the strength of the variations(energy) as a function of frequency. In other words, it shows at which frequencies variations are strong and at which frequencies variations are weak.
