    • 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。

    • PURPOSE: A cooperation terminal selection method and apparatus thereof are provided to measure link states of a cooperation terminal by broadcasting RTS(Ready To Send) message and by establishing a timer based on channel values. CONSTITUTION: A reception unit(810) receives help messages from a cooperation request terminal. The help message includes identification information of the cooperation request terminal, target RSS(Received Signal Strength), and a pilot signals. A timer establishment unit(820) establishes a timer based on the RSS of a target terminal, RSS change rates of the target terminal, and the target RSS. A transmission unit(830) transmits an RTS message when the timer is completed. A control unit(840) receives a CTS(Clear To Send) message from the cooperation request terminal.
    • 目的:提供一种协作终端选择方法及其装置,通过广播RTS(Ready To Send)消息和基于信道值建立定时器来测量协作终端的链路状态。 构成:接收单元(810)从合作请求终端接收帮助消息。 帮助消息包括协作请求终端的标识信息,目标RSS(接收信号强度)和导频信号。 定时器建立单元(820)基于目标终端的RSS,目标终端的RSS变化率和目标RSS建立定时器。 当定时器完成时,发送单元(830)发送RTS消息。 控制单元(840)从合作请求终端接收CTS(清除发送)消息。
