Realistic Vehicle Movement Models and Corresponding Radio Channel Parametrization for the Use of Positioning and Communications Studies

Abstract

Mobility of user equipment introduces significant effects on wireless channel parameters in the context of vehicle movement scenario. In recent years, mobility models being a way of redefining channel parameters in the field of vehicular communication channel has gained noticeable research focus. Furthermore, different performance aspects like throughput, reliability, availability as well as latency require analysis from both real life and simulation point of view. In the thesis scope, vehicle specific mobility models are selected based on algorithm simplicity, reliability and efficiency over other mobility models. In addition, the channel parameters are described and simulated taking user equipment mobility as well as different carrier frequency usage into ac-count. Besides, in the context of vehicular communication regarding different vehicle types it is important to converge mobility models in positioning studies. Moreover, tracking the user position with velocity estimates is simulated and analysed by using Kalman filter methodology to illustrate the effect of user equipment velocity on the filtering scenario. Furthermore, effect of base station geometry on channel performance with reference to the mobility path of user equipment in the context of different carrier frequency usage is simulated and discussed to portray variation in the channel throughput. Finally, different channel modelling parameters are considered maintaining contextual resemblance with the mobility models to analyse as well as simulate different scenarios related to vehicle mobility effect on channel parameters.
