A narrowband interference has a greater power spectral density. Thus it will bring more strong devastation to the DSSS system than a broadband one does.So it is difficult for DSSS system to ensure a high quality of communication by itself when strong interference exists, even communication may be intermitted.

窄带干扰(Narrow-Band Interference，NBI)由于其功率谱密度比宽带干扰高得多，所以它对DSSS系统的破坏性更强，当有强窄带干扰存在时仅靠系统自身的抗干扰能力很难保证系统高质量的通信，甚至可能造成系统通信中断。
