    • A device and method for eliminating narrow-band interference by way of windowing in a spread spectrum system, wherein the device comprises of a frequency spectrum transform unit, an interference elimination unit, an interference elimination control unit and a frequency spectrum inverse transform unit. Said method comprises the following steps: extracting N sampling points of data to perform frequency spectrum transform each time and obtaining N points of data; then updating control information, comparing the energy values of the N points with the threshold within the set time period to determine the number of narrow-band interference as well as the width and location of the interference; then determining the corresponding frequency domain adjusting window based on the width and location of the narrow band interference, obtaining the points within the window and the adjusted values of those points; with regard to the transformed N points during interference elimination process, setting the energy values of the points within the window during the current time period and the last period as the corresponding adjusted values, and then outputting the points after frequency spectrum inverse transform. The present invention can reduce adverse impacts of spectrum leakage on the capability for suppressing narrow-band interference.
    • 一种用于在扩频系统中通过窗口消除窄带干扰的装置和方法,其中该装置包括频谱变换单元,干扰消除单元,干扰消除控制单元和频谱逆变换单元。 所述方法包括以下步骤:提取N个数据采样点,每次执行频谱变换,获得N个数据点; 然后更新控制信息,在设定的时间段内比较N点的能量值与阈值,以确定窄带干扰的数量以及干扰的宽度和位置; 然后基于窄带干扰的宽度和位置确定相应的频域调整窗口,获得窗口内的点和这些点的调整值; 关于干扰消除处理过程中的变换后的N点,将当前时间段内的窗口内的点的能量值设定为相应的调整值,然后在频谱逆变换后输出点。 本发明可以减少频谱泄漏对抑制窄带干扰能力的不良影响。
