Embodiment

[0106] Scenarios considered by the present invention are as figure 1 As shown, the downlink cognitive satellite-ground coexistence network is divided into two parts: the satellite network and the ground network, and share the same spectrum resources. In a satellite network, a satellite (SAT, Satellite) with a single antenna sends a confidential message to a satellite terminal (PU, Primary User) when an eavesdropper (Eve, eavesdropper) tries to monitor the information sent by the satellite in the same beam . In the terrestrial network, the terrestrial base station (BS, BaseStation) is equipped with N t The root antenna communicates with the ground user (SU, Secondary User). Satellite terminals, eavesdroppers and ground users are all single antennas. The present invention assumes that there is co-channel interference in the cognitive satellite-earth coexistence network, that is, because the satellite SAT and the ground base station BS use the same channel when sending data, t...

Abstract

The invention relates to a safety transmission method of a cognitive satellite-ground network, and belongs to the technical field of the communication security. By designing a beam-forming scheme withthe minimum transmission power consumption on the ground base station, the signal and noise and noise interference ratio of a satellite link hacking terminal and the safety transmission of the satellite link terminal is realized under the condition of guaranteeing the communication quality of the ground user terminal. Compared with the prior art, the safety transmission method disclosed by the invention is suitable for the heterogeneous network architecture of the next generation 5G wireless communication, the safety transmission scheme with the minimum power consumption is provided for the BS under the scene that the information hacking is existent by reasonably designing the beam, and the normal communication of the system is guaranteed.

Description

technical field [0001] The invention relates to a secure transmission method, in particular to a secure transmission method for a cognitive satellite-earth network, and belongs to the technical field of communication security. Background technique [0002] With the increasing popularity of broadcast applications and multimedia services, satellite-ground cell coexistence heterogeneous networks have become the development trend of future communication networks, which can improve coverage and provide rich multimedia services for users anywhere, such as on-demand video streaming and TV broadcasting, etc. However, the exponentially increasing demand for multimedia content may lead to spectrum scarcity. To solve this problem, recently cognitive radio has been applied to the satellite-ground network to improve the radio spectrum efficiency, which is called the cognitive satellite-ground network. This satellite-ground coexistence network system based on the same frequency band is ...
