    • PURPOSE: A spurious signal elimination apparatus of a receiver and method thereof are provided to improve reception performance by detecting and eliminating spurious signals generated within the receiver. CONSTITUTION: A notch filter(220) eliminates signals of a specific frequency band for OFDM(Orthogonal Frequency Division Multiplexing) signals. A spurious signal analysis apparatus(250) detects the frequency location and bandwidth of spurious signals from a frequency domain signals. A host processor(300) calculates filter coefficient values by using the bandwidth and the frequency location. The host processor establishes the filter coefficient values of the notch filter by using the stored filter coefficient values of an LUT(Look Up Table).
    • 目的:提供接收机的伪信号消除装置及其方法,以通过检测和消除在接收机内产生的杂散信号来提高接收性能。 构成:陷波滤波器(220)消除用于OFDM(正交频分复用)信号的特定频带的信号。 寄生信号分析装置(250)从频域信号检测杂散信号的频率位置和带宽。 主处理器(300)通过使用带宽和频率位置来计算滤波器系数值。 主机处理器通过使用存储的LUT(查找表)的滤波器系数值建立陷波滤波器的滤波器系数值。
