Thus, the frequency domain adaptive filter is well suited to a multi - narrowband interference scenario, the paper studied frequency domain adaptive algorithms, carried out analysis and computer simulations. simulation results : for gold codes ds - ss signal of length 63, 4 interferences of signal to interference ratio ( sir ) 40 ub or 4 narrowband interferences of signal to interference ratio ( sir ) 40 db and frequency - spectrum bandwidth 12 percent of the whole bandwidth, the sir improvement is better than 20db
模擬結果指出，在輸入信號為干擾是4個等強度的多音干擾或4個頻譜帶寬占信號總帶寬12的強窄帶干擾（干信比為40db ）的擴頻信號（碼長為63的gold碼序列）情況下，演算法的干擾抑制比均優於20db 。 -
For rfi and narrowband noise interferences, this dissertation studies notch filter and spectrum equilibrium and uses them to suppress narrow jammings in signal domain
對于rfi和窄帶噪聲干擾，本文研究了頻域陷波和譜均衡兩種方法，並將之應用到信號域來抑制窄帶干擾。 -
After discussing this kind of filter in this paper in detail, the grads algorithm in time domain and frequency domain is set up when the change of frequency is slow, so it means the algorithm only process the narrowband interference what it changes slowly
論文對數字自適應外差濾波器進行了詳細的研究，建立了自適應外差濾波器的時域和頻域的梯度演算法，該演算法的推導使用了外差頻率變化緩慢的假設，這意味著該濾波器只能夠處理慢變的窄帶干擾。 -
