Problems solved by technology

[0004] From the above, it can be seen that the time slot design of Link16 has the following problems: Link16 uses frequency hopping, the frequency hopping sequence is fixed, and the update field of the frequency hopping sequence is not considered in the time slot structure, which cannot be applied to adaptive frequency hopping against strong interference System; the message body of Link16 adopts RS (31, 15) error correction coding, which reduces the system throughput rate, and the coding gain is not high; the introduction of RTT message greatly increases the protocol overhead, and cannot support high-speed data transmission of nodes in the network
At present, some studies...

Embodiment Construction

[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0034] The wireless network communication time slot structure determined by the present invention provides an efficient and practical time slot format for adaptive frequency hopping time division multiple access wireless network communication between multiple nodes. Such as figure 1 As shown, a method for determining the time slot structure of a wireless networking communication provided by the present invention, the steps are as follows:

[0035] (1) Determining the time slot structure: the time slot structure is divided into five subsections: synchronization word pulse package, TOD pulse package, propagation delay calculation section, data pulse package and transmission protection section;

[0036] (2) Determine the length of the time slot sub-segment:

[0037]There is a propagation delay calculation segment and a propagation protection segm...

Abstract

The invention provides a time slot structure determination method for wireless networking communication. The method comprises design methods of a synchronization word pulse packet, a time information TOD pulse packet and a data pulse packet in a time slot structure and is applicable to time-division multiple-access wireless networking communication adaptive to frequency hopping between multiple nodes. By means of the method, frequency hopping frequency sets are updated in real time, protocol overhead is substantially reduced, and coding gain is effectively increased, so high-bit-rate, anti-interference and robust multi-node networking communication is achieved.

Description

technical field [0001] The invention relates to a method for determining a time slot structure of wireless network communication, and belongs to the technical field of wireless network communication. Background technique [0002] It has become a typical model for multiple nodes to network wirelessly in space and cooperate with each other to complete tasks that a single node cannot or is difficult to complete. It is widely used in military and civilian applications, and is playing an increasingly important role. [0003] The Link16 data link in the United States can hinge multiple nodes together, adopt the architecture of no central node, and realize a certain task collaboratively. According to the address access protocol, each epoch (12.8min) is divided into 98304 time slots, which are allocated to each node in the network according to certain principles. Link16 can use different message encapsulation structures for each time slot. There are five encapsulation structures. T...
