Abstract:
1. A method for channel estimation in vehicle-to-environment communication, comprising a computing unit performing the steps of: generating a plurality of models of the environment influencing the vehicle-to-environment communication from parameters of vehicle-to-environment communication; ascertaining the quality of the models based on convergence of the parameters associated with each model; and monitoring the parameters to ascertain a course of convergence of the parameters over time, the course of convergence being ascertained by: wherein the plurality of models are used for channel estimation, wherein a typical environment is assigned to each model, and a model is selected, out of the plurality of models, for channel estimation based on the convergence of the parameters associated with at least one model out of the plurality of models, and wherein the course of convergence of the parameters for the model selected for channel estimation is classified, a value is assigned to each class, and, based on the value of the class, it is determined whether to make a switch with respect to the model selected for channel estimation, and if so, which model to switch to.
