Frequency-hopping spread spectrum 参考:https://en.wikipedia.org/wiki/Frequency-hopping_spread_spectrum 简介 跳频扩频(Frequency-hopping spread spectrum) (FHSS) 是一种通过在占据大频谱带的多个频率之间快速改变载波频率来传输无线电信号的方法。这些变化由发射器和接收器都知道的代码控制。FHSS 用于避免干扰、防止...
跳频技术 (Frequency-Hopping Spread Spectrum;FHSS)在同步、且同时的情况下,接受两端以特定型式的窄频载波来传送讯号,对于一个非特定的接受器,FHSS所产生的跳动讯号对它而言,只算是脉冲噪声。FHSS所展开的讯号可依特别设计来规避噪声或One-to-Many的非重复的频道,并且这些跳频讯号必须遵守FCC的要求,使用75个以上的跳...
What Are the Challenges of Frequency Hopping Spread Spectrum Technology? Spread-spectrum communications need greater bandwidth than when only a single carrier frequency is used. Also, one of the most problematic aspects of the technology is to initially synchronize the transmitter and receiver. Although...
Advantages of Frequency Hopping Spread Spectrum FHSS offers three main advantages over a fixed-frequency transmission: FHSS signals are highly resistant to narrowband interference because the signal hops to a different frequency band. Signals are difficult to intercept if the frequency-hopping pattern is...
