As one of the two basic modulation techniques used in spread spectrum communications, frequency hopping ( FH ) was originally designed to be. In the receivers of FH systems (Fig.
1), the frequency hopping is removed by mixing with a local oscillator signal, which is hopping synchronously. Traducir esta páginafrequency. For FH systems, pseudo-random frequency hopping during radio transmission minimizes the possibility of hostile jamming and unauthorized interception.
In the case of FH, which is the subject matter of this paper, the transmitter and the receiver synchronously hop across several carrier- frequencies.
