Afin de réduire la quantité d'interférences avec les cellules voisines dans les systèmes cellulaires, nous utilisons généralement des antennes de station de base (BS) qui ont des diagrammes de faisceau nets dans le plan vertical ; cependant, la distribution des ondes entrantes au niveau de la BS affecte le gain effectif des antennes BS qui ont un diagramme directionnel. Il nous faut donc clarifier les caractéristiques de la répartition des ondes entrantes. Une tendance récente est la diminution du rayon des cellules ; par conséquent, il est important de clarifier la répartition des ondes entrantes au niveau de la BS lorsque les stations mobiles (MS) sont situées à moins de 1 km de la BS. Dans ce rapport, nous évaluons les gains effectifs des antennes BS, qui sont calculés à l'aide du profil d'angle de puissance vertical (PAP) mesuré. De plus, nous examinons l’application d’un modèle simple d’onde entrante à l’évaluation des gains effectifs de l’antenne. Dans le modèle, la puissance moyenne des ondes entrantes est définie sur la fonction laplacienne et chaque onde est modifiée en une distribution log-normale. Le gain effectif de l'antenne calculé à l'aide du modèle concorde bien avec celui calculé à l'aide du PAP mesuré.

Abstract: In order to reduce the amount of interference to neighboring cells in cellular systems, we generally use base station (BS) antennas that have sharp beam patterns in the vertical plane; however, the distribution of incoming waves at the BS affects the effective gain of the BS antennas which have directional pattern. Therefore, we have to clarify the characteristics of the distribution of the incoming waves. A recent trend is decreasing the cell radius; therefore, clarifying the distribution of the incoming waves at the BS when mobile stations (MSs) are located within 1 km from the BS is important. In this report, we evaluate the effective gains of the BS antennas, which are calculated using the measured vertical power angle profile (PAP). Moreover, we examine the application of a simple incoming wave model to the evaluation of the antenna effective gains. In the model, the average power of the incoming waves is set to the Laplacian function and each wave is changed to a lognormal distribution. The antenna effective gain calculated using the model agrees well with that calculated using the measured PAP.
