dcterms:description
This paper deals with the impulse interferences in modern vehicles and assesses the suitability of establishing in-vehicle wireless links replacing standard data cable bundles. According to our experiments, the standard UMTS Long Term Evolution (LTE) is highly affected by impulse noise. We compare it with a novel 2D signal spreading method exploiting the orthogonal Walsh-Hadamard sequences in order to spread the transmitted signal in time and frequency. This method requires minor modification of the 3GPP LTE standard while no additional bandwidth nor noticeable computational power is required. In the presence of impulse noise, the novel 2D spreading method outperforms the standard compliant LTE significantly. As a system model, we used an open source LTE downlink simulator developed at Vienna University of Technology and the Middleton Class A impulse noise model.
