Description

technical field

[0001] The invention relates to wireless communication technology, and mainly refers to a digital trunking communication method with a control channel frequency hopping function. Background technique

[0002] Frequency hopping is one of the most commonly used spread spectrum methods. Its working principle refers to the communication method in which the carrier frequency of the transmission signal of the transmitting and receiving parties changes discretely according to a predetermined rule. controlled by random jumps. From the perspective of the time domain, the frequency hopping signal is a multi-frequency frequency shift keying signal; from the perspective of the frequency domain, the frequency spectrum of the frequency hopping signal hops randomly at unequal intervals on a wide frequency band.

[0003] Compared with fixed frequency communication, frequency hopping communication is more concealed and difficult to be intercepted. As long as the other party...
