Abstract :
A method of estimating the representative values of clutter height, the dominant parameter in Recommendation ITU-R P.452 for calculating clutter losses, is proposed. Our method estimates clutter heights from average building heights and terrain roughness of the area being investigated. We also derive the parameter values needed for the proposed method and discuss its validity by using the validation method of clutter losses that is based on 3D maps.
