窄带

Narrowband

在无线电中,窄带描述了信道的带宽不显着超过信道的相干带宽的信道。 在有线信道的研究中,窄带意味着考虑的信道足够窄,其频率响应可以被认为是平坦的。 因此,消息带宽将小于信道的相干带宽。 也就是说,没有信道具有完全平坦的衰落,但是如果可以假设平坦衰落,则无线系统的许多方面的分析被大大简化。 窄带还可以与音频频谱一起使用来描述占据窄频率范围的声音。 在电话中,窄带通常被认为覆盖频率为300-3400Hz。 In radio, narrowband describes a channel in which the bandwidth of the message does not significantly exceed the channel's coherence bandwidth. In the study of wired channels, narrowband implies that the channel over consideration is sufficiently narrow that its frequency response can be considered flat. The message bandwidth will therefore be less than the coherence bandwidth of the channel. That is, no channel has perfectly flat fading, but the analysis of many aspects of wireless systems is greatly simplified if flat fading can be assumed. Narrowband can also be used with the audio spectrum to describe sounds which occupy a narrow range of frequencies. In telephony, narrowband is usually considered to cover frequencies 300–3400 Hz.
