    • PURPOSE: An apparatus and a method for canceling interference in a mobile communication system are provided to group receiving signals to be suitable for a request BER(Bit Error Rate) of the mobile communication system and perform group-classified interference cancellation. CONSTITUTION: The first interference canceling unit(10) has a plurality of the first detectors(100) connected in parallel, a signal selector(200) and a subtractor(300). A plurality of the first detectors(100) receive a baseband signal. The signal selector(200) compares SIR(Signal to Interference Ratio) measurement values measured in a plurality of the first detectors(100) with a certain target SIR, and selects a reproduction signal reproduced in the first detector in which the SIR measurement value is greater than the target SIR. The subtractor(300) subtracts the reproduction signal selected in the signal selector(200) from the baseband signal. A last judging unit(20) receives the signal outputted from the first interference canceling unit(10), and performs hard bit decision.
    • 目的:提供一种用于消除移动通信系统中的干扰的设备和方法,以将接收信号分组为适合于移动通信系统的请求BER(误比特率)并执行组分类干扰消除。 构成:第一干涉消除单元(10)具有并联连接的多个第一检测器(100),信号选择器(200)和减法器(300)。 多个第一检测器(100)接收基带信号。 信号选择器(200)将在多个第一检测器(100)中测量的SIR(信号干扰比)测量值与特定目标SIR进行比较,并且选择在第一检测器中再现的再现信号,其中SIR测量值是 大于目标SIR。 减法器(300)从基带信号中减去在信号选择器(200)中选择的再现信号。 最后判断单元(20)接收从第一干扰消除单元(10)输出的信号,并执行硬比特判定。
