    • A device for determining interference by using a cyclic prefix and a method thereof are provided to determine interference occurring between the first and second networks by an interference determination unit, thereby preventing collision of a network signal. A signal receiving unit(310) receives the first signal of the first network and the second signal of the second network. A correlator(320) calculates a correlation value of the first cyclic prefix included in the first signal and a correlation value of the second cyclic prefix included in the second signal. An interference determining unit(330) determines whether interference occurs between the first network and the second network by using the correlation value of the first cyclic prefix and the correlation value of the second cyclic prefix. The interference determining unit determines an interference level.
    • 提供一种通过使用循环前缀来确定干扰的装置及其方法,以通过干扰确定单元确定在第一和第二网络之间发生的干扰,从而防止网络信号的冲突。 信号接收单元(310)接收第一网络的第一信号和第二网络的第二信号。 相关器(320)计算第一信号中包括的第一循环前缀的相关值和包括在第二信号中的第二循环前缀的相关值。 干扰确定单元(330)通过使用第一循环前缀的相关值和第二循环前缀的相关值来确定是否在第一网络和第二网络之间发生干扰。 干扰确定单元确定干扰电平。
