Abstract :
In this paper, we present a new method of on-site radiated emission measurement of train. This method is based on Blind Source Separation(BSS) which the prior knowledge of the source signals and transmission channels are unknown. By processing the received multi-channel mixed data, the source signals can be extracted only via two hypothetical conditions (statistical independence and non-gaussianity) in the complex electromagnetic environment under the influence of background noise and interference signal. It has been verified by the simulation that this method can effectively weaken the influence of external interference and improve the accuracy of the measurement which has great value to ensure the safe operation of train.
