Embodiment Construction

[0018] refer to figure 1 . In the embodiment described below, a star topology frame structure includes: non-central nodes B, C, D, E surrounding the central node A. In a star topology network, the transmission timeline between the central node A and the non-central nodes B, C, D, and E is divided into multiple radio frames RF, each radio frame RF contains multiple resource units RU, the first One resource unit RU carries the waveform sent by the central node, and the other resource units RU carry the waveform sent by the non-central node; each RU includes a control time slot, a pilot sequence and a service data area composed of a synchronization header, a pilot sequence and a control data area The business time slot and guard interval; the control data area in the control time slot adopts BPSK modulation, convolutional coding and GOLD code spreading; the business data area in the business time slot adopts QPSK modulation, convolutional coding and GOLD code spreading . The n...

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. technical background [0002] 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. have si...
