frequency-hopping spread spectrum
(foldoc) | Frequency-Hopping Spread Spectrum
FHSS
(FH, FHSS) A variation of {spread spectrum
communications} in which a sequence of pseudo random numbers
control a frequency synthesizer, generating different
carrier frequencies that "hop around" in the desired frequency
range. The receiver tunes to the same sequence of carrier
frequencies in synchronisation with the transmitter.
Frequency hopping spread spectrum was invented by Hedy Lamarr
("the most beautiful girl in the world", Samson and Delilah
etc.) and the composer George Antheil. They held a patent
filed in 1942.
