WT4 millimeter waveguide system: Spectrum estimation techniques for characterization and development of WT4 waveguide — II

In Part I techniques for reliably estimating the power spectral density function for both small and large samples of a stationary stochastic process were described. These techniques have been particularly successful in cases where the range of the spectrum is large. They are resistant to a moderate amount of contaminated or erroneous data. Here these procedures were demonstrated using examples from the development and analysis of the WT4 waveguide medium and compared to conventional techniques.
