Problems solved by technology

[0012] The technical problem to be solved by the present invention is: Aiming at the problems existing in the prior art, a dual-channel synchronization method for frequency hopping communication is provided. On the basis of the header method, through the ingenious design of the synchronization header at the transmitter, a short-period pseudo-random sequence is selected as the frequency control code. Through the design of the synchronization code pattern, the special pattern properties of the frequency hopping synchronization header are fully utilized to quickly realize Frequency synchronization, to solve the defects of TOD information data in the prior art using the synchronous header method, which occupies a large number of synchronous frequencies and the concealment of communication is not high

Abstract

The invention relates to a technology of the communication field, in particular to a two-channel synchronization method for frequency hopping communication. The invention aims at problems in the prior art, and provides a two-channel synchronization method for frequency hopping communication. According to the method, on the basis of a synchronized-head method and through smart design on synchronized-head transmission of a transmitting terminal, a short period pseudorandom sequence is selected as a frequency control code, and through design on a synchronization code pattern, the special pattern property of a frequency hopping synchronized-head is sufficiently utilized, frequency hopping synchronization is rapidly achieved, and the problems that in the prior art TOD information is needed when the synchronized-head method is utilized, a great number of synchronization frequency points are occupied, the elusiveness in communication is low, and the like, are solved. According to the invention, whether the frequency hopping synchronization is accomplished is confirmed by carrying out relevance calculation on the frequency hopping synchronized-head, so that connection is established on the transmitting and receiving terminals so as to achieve the design. The two-channel synchronization method is applicable to the field of frequency hopping communication.

Description

technical field [0001] The invention relates to the technology in the field of communication, in particular to a dual-channel synchronization method for frequency hopping communication. Background technique [0002] At present, wireless communication is an important field in communication, and frequency hopping technology is a technology often used in the field of wireless communication. The basic working principle of frequency hopping communication is that the carrier frequency of the communication signal changes according to a predetermined rule. Specifically, the carrier frequency in communication is controlled by a specific code and changes according to a predetermined rule. The third party cannot intercept the communication information without knowing the control code (frequency hopping pattern: under the control of the frequency hopping sequence, the law of carrier frequency hopping over time is called frequency hopping pattern). [0003] The key issue of frequency ho...
