Measurements and modelisation of shadowing cross-correlations between two base-stations

TL;DR

This paper presents measurements and a new model for shadowing cross-correlations between two base stations and a mobile, highlighting high correlation coefficients and their implications for network simulations.

Contribution

The paper introduces a simple shadowing model that incorporates both autocorrelation and cross-correlation, validated through measurements and simulations.

Findings

High cross-correlation coefficients can occur in practice.

The proposed model effectively simulates shadowing effects in network scenarios.

Abstract

Measurements in macrodiversity situations have been performed. Crosscorrelation of shadowing terms between two basestations and a mobile have been computed. It results that high cross-correlation coefficients may appear in practice. Afterwards, we propose a simple shadowing model, integrating both its autocorrelation and cross-correlation properties. Eventually, this model is used to compute simulations in some typical network cases.
