Measurement-based shadow fading correlation modeling for urban areas

摘要

This paper builds a shadow fading correlation model for urban area based on the measurement. The measurement principles and data processing methods are given in the measurement scheme. Through the measured data fitting to extract large scale fading parameters, analyze the impact of shadow fading correlation using semivariogram and verify the measurement accuracy of the shadow fading to use different data processing methods. The results show that there is an obvious short range shadow correlation in urban scenes, which provides the basis for the decision-making of the wireless communication network planning.
