Abstract

This paper depict. a measurement method that was developed to consistently characterize a mobile environment on the UHF band in terms of path loss. An automated data acquisition method is presented which consists of setting the sampling rate based on: a Rayleigh statistical distribution of the radio channel, the sounding instruments limitations and the intended mobile top speed. The Doppler effect is also taken into account when the resolution bandwidth is set. The paper also covers the acquired data processing technique that leads to the separation of the long and short term fading components using a moving mean filter.
