Abstract:
The power spectral density of the fading power of high-frequency radio waves and methods of esti mating this function are the subject of this report. Evaluations of the power spectral density estimates obtained by two different methods are made. The asymptotic low-frequency variation of estimates computed on a digital commputer and the expected value of estimates computed with an analog computer are derived. A comparison of the two methods is made and power spectral density estimates computed by both methods are shown. Power spectral density estimates are shown for eight different data samples. In general, the power density is con fined to frequencies below one cycle per second.
