Abstract (in Japanese) (See Japanese page) 
(in English) The EM noise emission in radio band from wire harnesses (radio noise) is evaluated by actual measurement test complying with CISPR25 in the development of automotive LAN. In this report, a radio noise estimation method is proposed. To estimate the noise voltage received by the antenna, the transmitter and the receiver circuits are modeled with S-parameters for common and differential modes. The modeling parameters for the transmitter circuit including the driver IC are obtained from the FFT of the communication signal voltages applying linear least squares method. In AM radio band the antenna voltage is estimated with accuracy of 10dB when the receiver circuit is substituted with a resistor network.
