taajuusiirtö
Taajuusiirtö, sometimes translated as frequency shifting or frequency hopping, is a technique used in telecommunications and signal processing to change the frequency of a signal. This is often done by modulating the original signal with a carrier wave whose frequency is varied according to a specific pattern. The pattern used for frequency shifting can be pseudorandom or follow a predefined sequence.
The primary purpose of taajuusiirtö is to improve signal reliability and security. In wireless communication systems,
Another significant application of taajuusiirtö is in spread spectrum communication. Frequency hopping spread spectrum (FHSS) is
