Abstract(in English) The electric car, a powerful impulsive noise from the inverter for switching a large current is generated. Reduction measures for this impulsive noise, communication in connected car, is indispensable to your trusted improvement in control. This impulsive noise is caused by leakage of the instantaneous high energy generated by the switching is emitted. The impulsive noise in the current signal transmission method, those ten dB greater number than in the white noise has become a standard design. Impulsive noise to white noise is -100dBm about at room temperature reaches +dBm. Impulse noise compared to white noise is of passive-based electronic fluctuations are those born from the electrical energy for performing electric control, the two noise there is a large power difference. Current transmission method designed optimally designed for white noise with equal power in all frequency band limitation using a BPF (Band Pass Filter) to minimize the noise is taking place. Pass band of the BPF is band-limited to the transmission signal one symbol ideally. Both of noise is also subject to this band-limited, but will be reduced, because the difference of energy is large, impulsive noise impact over several symbols. In this paper, the first to describe the nature of impulsive noise, to estimate the degradation due to impulsive noise. Then, we propose as the improvement method, impulse noise energy cut-off method using a switch, limiter, etc. S/N improvement method using a non-linear circuit, an impulse detection circuit a delay circuit.
