Adaptation of the Geometry-based reception angle models to different propagation scenarios

A significant difficulty in modeling the radio channel is related to adjustment the signal reception angle models to different environmental conditions. In this study, we show the solution to this issue on the example of the uniform elliptical with receiver outside model (UERO). The measurement data taken from open literature, delay and angle spread are the basis for the model adaptation. The relationship between the model parameters and delay spread that defines the type of environment is determined by least square method. Evaluation of fitting the model relative to the optimal values of the parameters that are included in literature, shows a slight increase error. This means that the presented method provides the adaptation of the model to statistical properties of the reception angle for the different propagation environments. The method of adaptation is described as an example UERO, however, it may be applied to other models.
