Abstract: Provided is a method for cancelling a nonlinear noise using an adaptive blanker based on a BPSK modulation system, comprising the steps of: estimating a narrow band middle turn parameter of an impulse noise by using a signal received during a certain period of time; calculating a threshold value by using the estimated narrow band middle turn parameter; operating a first blanker which cancels a noise from the received signal by comparing the threshold value with an absolute value of the received signal received at an arbitrary time point when a signal value provided from an SNR measurement device is smaller than the threshold value; and operating a second blanker which cancels a noise from the received signal by comparing the absolute value of the received signal with the sum of the threshold value and the signal value.

Abstract: PURPOSE: A magnetic field intensity changing device and a changing method thereof are provided to efficiently confirm whether a magnetic field intensity measured in a remote position from a magnetic field source satisfies a standard. CONSTITUTION: A magnetic field intensity changing device includes an input unit (402) and a control unit (401). The input unit receives a reference distance and a target distance from a magnetic field generating source. The control unit primarily compares the reference distance with a threshold value calculated according to a wavelength of an electromagnetic wave and secondarily compares the target distance with the threshold value. The control unit changes a reference magnetic field intensity defined for the reference distance to a magnetic field intensity for the target distance based on the comparison results to calculate a changed magnetic field intensity.
