Abstract: A method for impulsive noise mitigation using an adaptive blanker based on BPSK modulation system includes estimating narrowband Middleton parameters of impulsive noise from signals received for a fixed time period; calculating a threshold using the estimated narrowband Middleton parameters; operating the first blanker to suppress impulsive noise from the signal received at a given point of time through the comparison of the SNR value of the received signal and the threshold. Further, the method includes operating the second blanker to suppress impulsive noise from the received signal through the comparison of the summation of the threshold and the SNR value with an absolute value of the received signal, when the SNR value is above the threshold.

Abstract: A TEM cell includes an untapered region part configured to have a straight-line structure in which a cross-sectional area of an internal space is constantly maintained, tapered region parts coupled between both sides of the untapered region part and a connection part and each configured to have a tapered structure in which the cross-sectional area of the internal space is reduced toward the connection part, wherein a horizontal length of the tapered region part and a horizontal length of the untapered region part are determined in such a way as to reduce an electromagnetic field component in a direction vertical to a cross section of the untapered region part. The EMS evaluation performance of the TEM cell can be improved because an unnecessary electromagnetic field component can be reduced by designing the horizontal length of the untapered region longer than the horizontal length of the tapered region.
