Novel UWB in-vehicle channel measurement approach based on chirp pulse sounding signal

The ultra-wide band (UWB) in-vehicle channel measurement through sounding the channel with the chirp pulse signal is proposed in the paper. An UWB channel impulse response (CIR) estimator using de-convolution technique is presented to compare the measurement error of the UWB CIR generated from the chirp sounding pulse signal and the Gaussian pulse sounding signal, respectively. The noise resistance performance of the proposed UWB channel measurement approach is analyzed to verify the correctness of the measured channel data generated from the experiments.
