Airborne ultrashort wave multimedia communication system

Abstract

An airborne ultrashort wave multimedia communication system comprises a communication central station and a plurality of client terminal stations, wherein the communication central station is communicated with each client terminal station in an ultrashort wave wireless channel two-way mode, the communication central station, the client terminal stations and ultrashort wave wireless channels are together combined to form a star network framework, the communication central station and the client terminal stations are communicated directly, and the client terminal stations are mutually communicated and connected through the communication central station. The airborne ultrashort wave multimedia communication system is suitable for reliable stable networking communication under the conditions of helicopter airborne high-speed high dynamic and high-complexity terrain environments and supporting a plurality of communication nodes to construct multiple service communications such as networks, supporting images, telephones and data in a star networking mode. The airborne ultrashort wave multimedia communication system can be not only used under certain environments of landing ground of an aerospace engineering returning capsule, but also used under the conditions sun as salvage, mountain area rescuing, real-time reporting of city large-scale activities and competitions and the like.

Description

technical field [0001] The invention relates to wireless communication, in particular to an airborne ultra-short wave multimedia communication system suitable for helicopters and supporting multimedia communication networking. Background technique [0002] Airborne communication equipment refers to the electronic equipment used for communication on the aircraft. It mainly includes aircraft radio and intercom. Aircraft radio is the main tool for communication between aircraft and ground, aircraft and ships, and aircraft and aircraft. According to the wavelength, it can be divided into ultrashort wave, short wave, long wave and ultra long wave radio. Ultrashort wave radio stations (frequency ranges from 100 to 156 MHz and 225 to 400 MHz) are installed on various types of aircraft, usually working in the form of AM, and used for command and guidance communications within the line of sight. [0003] Multimedia communication refers to interactive communication that can simultan...

Problems solved by technology

[0005] Chinese patent 200610025877.1 discloses an "airborne wireless broadband image transmission system", which can be carried by a helicopter for wireless transmission, but the services it supports are only audio and video transmission, and it is point-to-point one-way transmission, and does not support multi-point two-way transmission Networking technology

However, what this system discloses is mainly OFDM-based channel modulation and demodulation technology for point-to-point one-way data communication, and does not involve multi-point two-way networking communication technology supporting multimedia services
