Yxx=Yxx'; You do not need to scale the output of the spectrum … Unlike the power spectral density (PSD), the peaks in the MSS reflect the power in the signal at a given frequency. The MSS of a signal is the Fourier transform of that signal's autocorrelation. Hmss = dspdata.msspectrum(Data) uses the mean-square (power) spectrum data contained in Data , which can be in the form of a vector or a matrix, where each column is a separate set of data. Answers (1) In a typical modulation (whether it is OFDM or something else) you have a local oscillator (LO) that upconverts the baseband signal to the desired carrier frequency. This LO has something … Power spectral density (PSD) estimation: MATLAB algorithm implementation for array signal processing and test validation March 2016 DOI: 10.13140/RG.2.2.31347.02088 If you were wondering about the units for the psd function, it is a spectrum. This means the x-axis is a frequency domain(1/seconds = 1Hz).

Default values for other properties of the object are shown below: View MATLAB Command This example shows how to obtain nonparametric power spectral density (PSD) estimates equivalent to the periodogram using fft. The examples show you how to properly scale the output of fft for even-length inputs, for normalized frequency and hertz, and for one- and two-sided PSD estimates. Even-Length Input with Sample Rate pxx = periodogram(x) returns the periodogram power spectral density (PSD) estimate, pxx, of the input signal, x, found using a rectangular window. When x is a vector, it is treated as a single channel. pxx = pwelch (x) returns the power spectral density (PSD) estimate, pxx, of the input signal, x, found using Welch's overlapped segment averaging estimator. When x is a vector, it is treated as a single channel.
