Statistical characterization of the field strength location variability for the new digital radio services in the Medium Wave band

摘要

This paper analyzes the field strength location variability in the Medium Wave band. Field data from an experimental transmission and statistical inference techniques are used in the study. Several reception scenarios are considered, attending to the main causes of the field strength fluctuations. The paper exposes results for the statistical characterization of both large scale variations and local variability, and useful values for coverage area estimations are given. A proper characterization of the location variability is necessary for the accurate system planning of the new digital radio services at this frequency band.
