Abstract

The invention discloses a narrow-band interference resistance method and device in a frequency hopping burst communication system, and a storage medium. The method comprises the steps of: according toa plurality of frequency hopping points and a plurality of frequency hopping time slots, sending or receiving data on the frequency hopping points corresponding to the frequency hopping time slots during each frequency hopping time slot in accordance with transceiving types corresponding to the frequency hopping time slots; detecting the narrow-band interference in each receiving time slot of a plurality of frequency hopping time slots to detect interference frequency points of a plurality of frequency hopping points; and when the data needs to be sent, sending the data to a second device during the sending time slots corresponding to the frequency hopping points except the interference frequency points. By adoption of the method, the sender and the receiver are unnecessary to shake handto transmit the interference frequency point information; the frequency hopping sequence is unnecessary to be changed; the system overhead is low; the utilization ratio of the channel is high; and theproblem of the narrow-band interference in the frequency hopping burst communication system is solved efficiently.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an anti-narrowband interference method, device and storage medium in a frequency hopping burst communication system. Background technique [0002] At present, the use of digital radio stations in UAV data links and agricultural machinery automatic driving navigation data links is becoming more and more extensive. Due to the lack of site, frequency and protocol coordination of digital radio stations, problems such as serious co-channel interference have occurred in digital radio stations. The data transmission station can use the frequency hopping burst communication technology to make the communication frequency point change continuously according to the preset frequency hopping pattern, so that although the narrowband interference in most adjacent areas can be avoided, when the frequency points in the adjacent area coincide with the When a certain frequency point...
