频谱带宽 meaning in Chinese

spectral bandwidth

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
仿真结果指出，在输入信号为干扰是4个等强度的多音干扰或4个频谱带宽占信号总带宽12的强窄带干扰(干信比为40db )的扩频信号(码长为63的gold码序列)情况下，算法的干扰抑制比均优于20db 。
