Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… … Wikipedia
Carrier current — is a method of low power AM broadcasting that does not require a broadcast license in the United States, but is allowed on the campus of any school, so long as the normal FCC Part 15 Rules are adhered to when measured at the edge of the campus.… … Wikipedia
Carrier recovery — A carrier recovery system is a circuit used to estimate and compensate for frequency and phase differences between a received signal s carrier wave and the receiver s local oscillator for the purpose of coherent demodulation. Example of QPSK… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
Frequency mixer — This article is about non linear mixing operating in the frequency domain. For other types of mixers, see electronic mixer. Frequency Mixer Symbol. In electronics a mixer or frequency mixer is a nonlinear electrical circuit that creates new… … Wikipedia
Frequency-division multiplexing — (FDM) is a form of signal multiplexing where multiple baseband signals are modulated on different frequency carrier waves and added together to create a composite signal. Non telephoneFDM can also be used to combine multiple signals before final… … Wikipedia
Frequency-division multiple access — or FDMA is an channel access method that is used by radio systems to share a certain radio spectrum between multiple users. The users are individually allocated one or several frequency bands, allowing them to access the radio system without… … Wikipedia
frequency modulation — n. 1. the variation of the frequency of a carrier wave in accordance with the signal being broadcast 2. a broadcasting system that uses this: Abbrev. FM: Cf. AMPLITUDE MODULATION … English World dictionary
Carrier system — In telecommunication, a carrier system (loosely, a synonym with carrier) is a multichannel telecommunications system in which a number of individual channels (e.g. data, audio, video or combination thereof) are multiplexed for transmission. The… … Wikipedia
