Apparatus and method for evaluating statistical interference concerning multi-source noise environment of electromagnetic zone

摘要

An apparatus and method for evaluating statistical interference concerning a multi-source noise environment of an electromagnetic (EM) zone are disclosed. The apparatus for evaluating statistical interference may include a receiver to receive an EM wave in a preset frequency band, a spectrum analyzer to analyze the received EM wave and to measure interference in the preset frequency band, a frequency selector to select an interest frequency in the frequency band based on a level of the measured interference, an amplitude probability distribution (APD) measurement unit to measure an APD of an interference signal with respect to the interest frequency, and a comparator to compare the measured APD to a preset limit and to draw a probability of the limit or higher of interference occurring.

1. An apparatus for evaluating statistical interference, the apparatus comprising:
a receiver to receive an electromagnetic (EM) wave in a preset frequency band; a spectrum analyzer to analyze the received EM wave and to measure interference in the preset frequency band; a frequency selector to select an interest frequency in the frequency band based on a level of the measured interference; an amplitude probability distribution (APD) measurement unit to measure an APD of an interference signal with respect to the interest frequency; a comparator to compare the measured APD to a limit and to determine a probability of a limit of interference or higher occurring; and a limit calculation unit to calculate the limit based on an interference evaluation model in consideration of a multi-source noise environment of a region defined as the same EM wave environment.
