Abstract

The invention discloses a multi-beam scatter communication device and a multi-beam scatter communication method, and relates to scatter communication antenna rapid alignment and multi-node centerless ad-hoc network technologies in the communication field. The communication device comprises a GPS (global positioning system), a monitoring unit, an indoor unit and an outdoor unit, wherein the indoor unit realizes modulation-demodulation for scattering signals and control for a centerless ad-hoc network protocol, provides a self-organizing and self-healing network function for nodes, and carries out information transmission. The communication method adopts a mode of sector beam switching, can automatically realize the whole process of antenna alignment, link establishment and information transmission of a scatter communication link, and has the remarkable characteristics of simple operation and convenient use. The method disclosed by the invention not only can support point-to-point communication and point-to-multipoint communication, but also can support centerless ad-hoc network communication among the multiple nodes, has high self-organizing, self-healing and anti-interference abilities, and is extremely applicable to medium/short-range small-capacity scatter communication.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-beam scattering communication device and a communication method. Background technique [0002] Difficulty in antenna alignment is common in scatter communication at present. Scattering communication devices mostly use narrow-beam antennas. When establishing a communication link, manual alignment is used, and measurement instruments are needed for assistance. The entire process is complex and time-consuming, and the alignment accuracy depends on the technical level of the operator. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies in the above-mentioned background technology. On the basis of scattering over-the-horizon communication, the sectoral beam switching mode of multi-beam antennas is introduced, which can significantly improve the antenna automatic alignment and centerless self-alignment of scattering comm...
