Many translated example sentences containing " frequency hopping " – Spanish- English dictionary and search engine for Spanish translations. Once in track mode of operation, a frequency hopping hysteresis ensures against erroneous detection of signal loss by tracking the transmitter hopping pattern for.

Frequency Hopping (FH) communication is a technology of spread spectrum communication. A novel method on smoothed-pseudo Wigner-Ville Distribution (SPWVD) to extract single-source zone of the synchronous-networking frequency hopping ( FH). Frequency hopping is the repeated switching of frequencies during radio transmission and is used to minimize the effects of unintentional.
