Abstract:
A re-generation method of radiated disturbances from multiple noise sources using statistical approach is suggested. The radiated disturbances from multiple noise sources consisting of an electric board and a Plasma Display Panel (PDP) TV are investigated. The frequency spectrum and the Amplitude Probability Distribution (APD) of radiated noises are measured. The radiated magnetic field from each noise source is measured below 30MHz, and then APD measurement is progressed at the frequencies where the noise sources radiate high disturbances in common. A sequence of noise pulses is observed from PDP TV, and the behavior of the APD of the electric board noise is similar to the Gaussian noise. The parameters of the disturbances are extracted using the Middleton’s class A noise model and approximate empirical method. From the extracted parameters, random noise data is re-generated and radiated using a signal generator and antenna. APD Comparison of the measured multiple noises and re-generated noises is performed. The results show that the re-generation noises are well matched to measured noises. The re-generated noise can be applied to the performance evaluation of communication systems against non-Gaussian multiple noises circumstances.
