One way in which spread spectrum is implemented is through frequency hopping, a technique in which a signal is transmitted in short bursts, “hopping” between frequencies in a pseudo-random sequence. Both the transmitting device and the receiving device must be aware of the frequency sequence. ...
WHAT IS SPREAD SPECTRUM?D'Aquino, Rita
The use of spread spectrum has increased over the years due to deregulation, and it is used in a wide array of telecommunications and communication fields. It was first used in the military in the 1950s for secure communications, and usage spread in the early 1980s for use in many satellit...
What is spread-spectrum technology?Alan LowneSaelig Company Inc
In telecommunications, spread spectrum is a technique where a signal's original bandwidth is spread across frequencies, widening its bandwidth. This process can create increased security of communications, a resistance to interference and jamming, and an LPI (low probability of interception) by ...
Chirp Spread Spectrum What is it? The Chirp, or Chirp Spread Spectrum (CSS), denotes long-range radio frequency technology designed for wireless communication. It is used to identify and monitor indoor and outdoor locations of people and assets. How does it work? This technology is employed ...
Frequency-hopping spread spectrum (FHSS) is repeated switching of carrier frequency during radio transmission to reduce interference and avoid interception.
Chirp spread spectrum (CSS) is based on a spread spectrum system of the method, which makes use of modulated chirp pulses of wideband linear frequency and its complete assigned bandwidth to put out and transmit a signal for the reason that the chirps make use of a broadband of the spectrum...
DSSS is a spread spectrum modulation technique used for digital signal transmission over airwaves. It was originally developed for military use, and employed difficult-to-detect wideband signals to resist jamming attempts. It is also being developed for commercial purposes in local and wireless networks...
