Embodiment Construction

[0034] Below, combine Figure 1 to Figure 4 The present invention is further described.

[0035] A parameter-agile TDMA communication method, comprising the following steps:

[0036] (1) The spaceborne equipment sends frequency hopping time information on the satellite in the downlink, and each ground station extracts the frequency hopping time information as the burst time reference of the TDMA system of each ground station;

[0037] This information is a long-period time information, through which the corresponding frequency hopping frequency value at each moment can be calculated in the frequency hopping pattern consistent with the satellite and the ground, so as to realize frequency hopping synchronization. Since all earth stations are synchronized to this time reference, the time synchronization of the entire network is also completed.

[0038] (2) One of the ground stations is set as the master station of the TDMA system in each ground station; the master station perfo...

Abstract

The invention discloses a parameter agility time division multiple access (TDMA) communication method, and relates to a networking and service transmission technology for a frequency hopping TDMA satellite communication system. The frequency hopping TDMA satellite communication system is networked by methods such as variable-rate frame structure configuration, small and large station variable-rate intercommunication and modulation and demodulation parameter agility; on the basis of networking, frequency hopping transmission and receiving and variable-rate emergency packing of service data are realized; and a technical effect of intercommunication of services under hybrid networking of small and large stations is achieved. The method has the characteristics of reliable control method, high station adaptability and high system resource utilization rate and is particularly suitable for networking and service transmission processes for the TDMA frequency hopping satellite communication system based on satellite frequency hopping forwarding.

Description

technical field [0001] The invention relates to the networking and service transmission technology of a frequency-hopping TDMA satellite communication system, and is particularly suitable for the networking and service transmission process of the TDMA frequency-hopping satellite communication system based on satellite frequency-hopping forwarding. Background technique [0002] The frequency hopping TDMA satellite communication system has the flexible access and switching capabilities of the general MF-TDMA system, efficient satellite resource utilization and network expansion capabilities, and can better meet the network communication between medium and low speed nodes. At the same time, due to its frequency hopping communication characteristics, it has strong anti-interference ability and confidentiality, and is especially suitable for military satellite applications. [0003] However, when the frequency hopping TDMA satellite system is networked, in addition to business da...
