Channel characterization of mobile signal at 11 GHz

Abstract

For effective mobile satellite communications system design, it is necessary to know quantitatively the channel characteristics such as signal fading due to multipath. Such characteristics can be studied by the statistical distribution of the received signal envelope. A polynomial model is proposed to estimate the path loss of the mobile signals at 11 GHz. Also, variability of the probability density function (PDF) of the received signal power on various parameters has been investigated. The polynomial model for path loss agrees well with the measured data. The investigations on the channel characterization estimate the PDF of the channel for a variety of statistical parameters, which are directly useful for mobile system designers.
