Description
Summary:In this paper, we present a system simulator that can assess the performance of a direct measurement Tire Pressure Monitoring System (TPMS) in various operational scenarios. We also discuss the following capabilities of the simulator: (1) modeling the wireless channel characteristics experienced by the signals between various transmitters and the receiver of a given vehicle, (2) modeling intra-vehicular electromagnetic interference (EMI) as experienced by the wireless signals, and (3) quantifying the impact of wireless channel characteristics and intra-vehicular EMI on the system packet error rate (PER). Using quantitative results for hypothetical simulation scenarios, we demonstrate the impact of different levels of Additive White Gaussian Noise (AWGN) and Amplitude Modulated (AM) Noise on the system PER performance.
