This paper proposes a coverage area prediction method for extremely reliable in-car MB-OFDM UWB communication. Since sensor and control networks inside a car require extremely high quality of service (QoS), it is almost impossible for computer simulations to provide very low bit error rate (BER). In the proposed approach, very low BER performance is obtained by approximating the simulated BER with simple exponential functions thanks to the fact that coded MB-OFDM UWB system does not theoretically introduce any error floor. In other words, once the simulated BER can be transformed into a simple mathematical formula such as exponential function, the coverage area can be predicted irrespective of the target QoS. By using this approach, we demonstrate the coverage area to satisfy the BER of 1 × 10-12.
