frequencyhopped
Frequency-hopped communication refers to a spread spectrum modulation technique used in wireless communication systems to improve resistance against interference, jamming, and eavesdropping. In this method, the carrier frequency of the transmitted signal rapidly switches between a set of discrete frequencies, following a predetermined or pseudo-random sequence known as a hopping pattern. Each frequency in the sequence is used for a short duration, typically called a *hop time*, before switching to the next.
The core principle behind frequency hopping is to distribute the signal energy across a wide frequency band,
One of the key advantages of frequency-hopped systems is their ability to mitigate multipath fading, where
Frequency-hopped spread spectrum (FHSS) is a specific implementation of this technique, standardized in communication protocols like
