What is a spread spectrum transmission?
Spread spectrum is a form of wireless communications in which the frequency of the transmitted signal is deliberately varied. This results in a much greater bandwidth than the signal would have if its frequency were not varied.
Which is better FHSS or DSSS?
The DSSS method of modulation has a higher rate of transmission than the FHSS method. In terms of the signal transmission rate, DSSS is superior. However, DSSS is vulnerable to electromagnetic interference and noise produced by devices operating at the same frequency band.
What is FHSS and DSSS?
Frequency hopping spread spectrum (FHSS) and direct-sequence spread spectrum (DSSS) are two methods of spreading a transmitted spectrum over a wide bandwidth, so that the energy at any particular frequency is not detectable without special foreknowledge of the spreading technique.
Is spread spectrum still used?
However, due to advantages like anti-jamming and reduced crosstalk interference, spread spectrum technologies were adopted for wireless communication technologies as well. From mobile communication to WiFi connectivity, the spread spectrum technique is now used as a significant technology in systems design.
