A terminal for forming a time slot data frame compatible with a data link and its working method

Abstract

Provided are a forming terminal of a time slot data frame compatible with a data chain and a working method of the same. Based on correlation of data redundancy and requirements for communication quality of service, under the condition of constant radio-frequency bandwidth, the terminal can visually and clearly display the formation process of the time slot data frame through the coordination of parts. The received service data is analyzed, and an appropriate encoding, a modulation, a spread spectrum combined technology and a data encapsulation formats are selected, then the combined technical information is creatively mapped to a fine synchronization field stuffing bits for the time slot data frame, so that when the receiving terminal is in the fine synchronization, the encoding, the modulation and the spread spectrum subsequent combined technical information of the subsequent received data are obtained, which can shorten the preprocessing time of the received data, satisfy the requirement of anti-interference, confidentiality, real-time and coverage of the data chain, and further enhance the adaptability of the data chain to future complex environments and improve system throughput. The forming terminal of the time slot data frame compatible with the data chain has the advantages of being compact, reasonable and artful in structure, being simple, convenient and easy to operate, and being promising in application prospect.

Description

technical field [0001] The present invention relates to a terminal for forming a time slot data frame compatible with a data link and a working method thereof, to be precise, relates to a JTIDS / Link16 tactical data link using coded modulation, spread spectrum communication, bit mapping and time slot data A forming terminal encapsulated into a time slot data frame and a working method thereof belong to the technical field of wireless communication. Background technique [0002] The data link is a kind of communication network as a bridge, information processing as the center, connecting various combat systems such as perception systems, command automation systems, fire strike systems and information attack weapon systems distributed on land, sea, air and space. An organic whole information network composed of various elements is also the basis for comprehensive integrated construction and digital integration of sensors, command and control systems, and weapon platforms in the...

AI Technical Summary

Problems solved by technology

[0008] Although the currently widely used tactical data link JTIDS / Link16 has five data encapsulation structures, it can still meet the needs of battlefield communication for the time being. However, with the rapid development of digital, informatization, and intelligent technologies, the original communication technology It is still difficult to deal with new issues such as the transmission of big data services (such as video information services), real-time data updates, and multi-platform integration.
