POWER SPECTRAL DENSITY ESTIMATES OF THE FADING OF HIGH FREQUENCY RADIO WAVES

摘要

The power spectral density of the fading power of high-frequency radio waves and methods of estimating this function are the subject of this report.nEvaluations of the power spectral density estimates obtained by two different methods are made. The asymptotic low-frequency variation of estimates computed on a digital computer 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 com¬puted by both methods are shown.
