Embodiment Construction

[0019] refer to figure 1 . According to the present invention, the radio frame RF (Radio Frame) in the coverage area is divided into a plurality of radio frames: RadioFrame#0...RadioFrame#1, RadioFrame#+1...RadioFrame#N, distributed around the central node A connected non- The central nodes B, C, D, and E form a centralized control network topology. The central node A and non-central nodes B, C, D, and E of the aircraft nodes participating in the networking form a star topology, and each resource unit RU contains One control time slot TS0 carrying control information and multiple service time slots TS1, TS2, TS3, TS4 carrying service information and guard intervals; in a star topology network, each node communicates through the central node, and the center Node A interacts with non-central nodes B, C, D, and E through wire frame RF. Each wireless frame RF contains multiple resource units RU, where the first resource unit RU0 carries the waveform sent by the central node, and ...

Abstract

The invention provides a star topological frame structure, aims at providing a star topological frame structure having certain antijamming capability and being suitable for distributed aircraft networking, a networking process of the star topological frame structure is simple and rapid and the number of the networking nodes for the star topological frame structure is flexible. The star topologicalframe structure is implemented through the following technical scheme: in a network of the star topological frame structure, a transmission timeline between a central node A and noncentral nodes B, C, D and E is divided into a plurality of radio frames RF, each radio frame RF comprises a plurality of resource units RU, the first resource unit RU bears a central node sending waveform, the other resource units RU bear a noncentral node sending waveform; each RU comprises a control time slot composed of a synchronous head, a guiding sequence and a control data area, a service time slot composedof the guiding sequence and a service data area, and a protection interval; BPSK modulation, convolutional encoding and GOLD code spreading are used for the control data area in the control time slot;and QPSK modulation, convolutional encoding and GOLD code spreading are used for the service data area in the service time slot.

Description

technical field [0001] The invention is applicable to the star topology frame structure in the field of wireless communication, and in particular relates to a frame structure applied to a distributed aircraft communication network. [0002] technical background [0003] The important feature of distributed aircraft is the "clustering" and "coordination" of work. Only when multiple aircrafts in spatial distribution form a cluster and cooperate closely can a unified distributed system be formed, so as to fully explore the application potential of distributed aircraft. , beyond the traditional single aircraft. The basis of "clustering" and "synergy" lies in: realizing smooth information exchange through distributed aircraft communication networking. Compared with the traditional single aircraft system, the distributed aircraft system in the form of "group", "cluster" and "formation" has the advantages of low cost, high performance, flexibility, reliability and invulnerability. ...
