In the receiving system, the narrow-band interference filter is introduced in order to reduce the background light, increase the signal transmission rate, and improve the signal-to-noise ratio.

在接收系统中，引进窄带干涉滤光片，减少背景光的干扰，增加信号光透射率，改善信噪比。

Finally, the S-CDMA and the adaptive nonlinear filter techniques are used to restrain the impulse interference and the narrow-band continuous wave interference.

最后，采取了同步码分多址技术和非线性自适应滤波技术来抑制冲击干扰和窄带连续波干扰。

Technology based on adaptive-filter, transform domain, code-aid and so on offer reliable and effective tool to the narrow-band interference suppression.

自适应滤波、变换域技术、码辅助技术等多种研究工具的引入更为窄带干扰的抑制提供更多可靠而有效的手段。
