Abstract

Developing an accurate wideband vehicular channel model is a key issue for the transmission scheme and protocol design of vehicular communications. Although finite-state Markov chain (FSMC) has been extensively investigated, most of the literature about FSMC modeling only considered channel fading in the time domain or frequency domain. Only few FSMC channel models describing channel fading in both the time and frequency domains lack the support of measurement data. In this paper, we propose an FSMC model in both time and frequency domain for vehicular channels based on real measurements. We validate the accuracy of steady state probability (SSP) of the proposed model via real measurement data. And we also discuss the influence of different subband partitions and the size of the modeling region on multi-subband interval change probability (MICP). The conclusion of this paper can be used in future FSMC modeling for the non-stationary wideband channel.
