A Synchronous Frequency Hopping Orthogonal Networking Method Based on Frequency Point Grouping

Abstract

The invention discloses a synchronous frequency hopping orthogonal networking method based on frequency point grouping. For a communication system including N subnets, each subnet is composed of a master and a slave. The orthogonal networking method Including: S1. Set the number of each subnet, the number is 0~N-1; S2. For the master and slave of each subnet, use the TDMA superframe structure to allocate network time slots, so that the master and slave of each subnet The slaves occupy different time slots statically, and the master and slaves are at f 0 ~ f K‑1 Synchronous frequency hopping within these K frequency points; S3. In any communication time slot, divide K frequency points into N groups, numbered Q 0 ~Q N‑1 , each group contains K 1 frequency points, and assign frequency hopping frequency points according to the subnet number, so that the frequency hopping patterns of N sets of equipment at the same time are orthogonal and do not interfere with each other. Based on the grouping of frequency points, the present invention can make the frequency hopping patterns of each subnetwork orthogonal at the same time, so that the frequency hopping frequencies of each subnetwork do not collide at the same time, and do not cause mutual interference between networks.

Description

technical field [0001] The invention relates to networking communication, in particular to a synchronous frequency hopping orthogonal networking method based on frequency point grouping. Background technique [0002] Frequency hopping communication is the most widely used and most effective technology in shortwave communication anti-jamming technology. The use of frequency hopping multiple access communication network greatly improves the anti-intercept ability and anti-interference ability of frequency hopping signals, which can well guarantee the security of transmitted information. And because the frequency hopping multiple access communication network has the advantages of strong anti-interference ability, low intercept probability, low detection probability, etc., it has a good inhibitory effect on frequency selective fading. When frequency hopping communication is used for networking, all devices with the same frequency hopping pattern are grouped in the same network....
