(2023) An enhanced approach to virtually increase quasi-stationarity regions within geometric channel models for vehicular communications. IEEE Antennas and Wireless Propagation Letters, 22(9), 2180-20184. https://doi.org/10.1109/LAWP.2023.32810811536-122510.1109/LAWP.2023.3281081https://academica-e.unavarra.es/handle/2454/46367Vehicular communication channels are intrinsically non-stationary, as they present high mobility and abundant dynamic scatterers. Quasi-stationary regions can assess the degree of non-stationarity within a determined scenario and time variant observation of the channel can be extracted. These regions can aid geometrical models as to increase channel sampling intervals or to develop hybrid stochastic-geometric channel models. In this work, a new methodology for the use of virtual quasi-stationary regions within geometric channel models is proposed, in order to leverage the inherent location information to virtually increase their size. Overall, the use of delay-shifted channel responses improves the mean correlation coefficient between consecutive locations, ultimately reducing computation time for time-variant geometric channel models.application/pdfeng© 2023 IEEE.
