Characterization and Simulation of an OFDM-Based Automotive Bus System

Abstract

For the system performance of an OFDM-based bus system in an automotive environment, the communication channel plays a very important role. To characterize the complete system, a precise measurement of the OFDM channel is required. Further, the allocation of frequency bands for different user nodes as per their requirements opens the possibility to consider different transceiver classes optimizing the utilization of communication links. This work presents the simulation of a full bandwidth OFDMA system, based on a channel which is characterized by using the measurement data. Some discussions and results for low bandwidth receiver class are also presented.
