LTE Link Level Performance Evaluation Using Stochastic Channel Models for V2X Communication

This paper presents an evaluation of the Long Term Evolution (LTE) link level performance for vehicular communication. For this, doubly-selective stochastic channel models originally derived for IEEE 802.11p networks are adapted according to the LTE system characteristics. These modified channel models are implemented into a LTE link level simulator. By comparing the simulation results with results obtained using classical cellular channel models it is shown that a more detailed modeling of the channel dynamics typical for vehicular communications is of great importance. Moreover, the comparison with the physical layer performance of an IEEE 802.11p system shows good potential to utilize LTE for vehicular applications or as part of a hybrid communication system.
