Digital communication station device with multi-carrier frequency hopping

Abstract

The invention discloses a digital communication station device with multi-carrier frequency hopping, comprising a communication carrier random indication unit, a baseband processing unit, a transceiver frequency conversion unit, a communication carrier searching unit and a duplexer. According to the scheme of the invention, in a station communication process, the communication carrier random indication unit randomly changes indication information to ensure that the communication carrier frequency is in a hopping state, a communication channel that loads voices and data is also in a random hopping state in a communication bandwidth, and a pseudo noise channel disguises and conceals the communication channel; and the multi-carrier frequency random hopping mode improves the anti-interferenceability of communication, avoids the defects of poor anti-interference ability and easy interception of existing analog communication stations and digital communication stations in a complex electromagnetic environment, also solves the problems that need to be solved in an actual frequency hopping communication process, and is applicable to data transmission and voice communication in various confidential anti-interference scenes such as civilian private network communication and military communication.

Description

technical field [0001] The invention relates to the technical field of wireless communication or communication countermeasures, in particular to a digital communication station device with multiple carrier frequency hopping. Background technique [0002] Communication radio has a wide range of applications in both civilian and military fields, and is an indispensable communication tool. Due to the single fixed-frequency carrier and modulation method, traditional communication stations have many defects such as poor anti-interference ability, easy interruption of communication, and easy interception of communication. In some urgent and important occasions or military scenarios, these shortcomings are intolerable. [0003] Fixed-frequency analog communication station is the most common form of communication station (such as figure 1 As shown), many private network radio stations use this method to realize point-to-point communication. Each communication can choose a channel ...
