Based on the analysis of theory data, this paper brings the base model of wireless narrow-band channel for air-based missile image transmission system.
在理论分析的基础上，结合对大量试验数据的分析，给出了空基型导弹图像传输系统无线窄带信道的基本模型。
Your radio transmission, furthermore, would probably be a narrow-band signal, to distinguish it from other transmissions in neighboring bands as well as naturally occurring noise.
此外，你的无线电信号可能会是一个窄带信号，以区别于邻近频带中其他的自然杂波。
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。
At last it discusses the dual-mode transmission technology of the Ultra Narrow Band Modulation and the FM combination.
最后着重讨论了超窄带调制与FM结合的双模式传输技术。
We can think of such a transmission as a combination of many narrow band signals at adjacent frequencies, all broadcast simultaneously as a single broad-band signal.
我们可以把这种信号想象成在很多很多个窄频带上同时的播报同一个信号的组合。
