The invention proposes a beam design method based on security and energy efficiency in a satellite-ground integrated network, which is used to solve the technical problem of low system security and energy efficiency in the downlink of the existing satellite-ground integrated network. The steps are as follows: firstly, use analog precoding to form high-gain directional beams, then design digital precoding to eliminate interference between users, and finally, propose a joint optimization problem of transmit power and power splitting coefficient, the goal of which is to maximize the system Safety and energy efficiency, while satisfying the QoS constraints of each user, the interference constraints of satellite ground stations and the power consumption constraints of base stations; in order to solve this problem, an iterative algorithm based on Dinkelbach and continuous convex approximation SCA is proposed to obtain the solution of the problem, The convergence efficiency of the system security transmission rate is improved. The present invention adopts the millimeter-wave large-scale MIMO-NOMA system combined with SWIPT technology in the ground network, and the base station provides services to multiple users and protects the satellite ground station from interference.
Description
technical field [0001] The invention relates to the technical field of safety and energy efficiency of communication network transmission, in particular to a beam design method based on safety and energy efficiency in a satellite-ground integrated network. Background technique [0002] The fusion of satellite communication network and terrestrial 5G network is considered to be a promising heterogeneous network architecture. The two together form an integrated communication network with seamless global coverage, which is an important direction for future communication development. In the 5G network, the application of millimeter wave, massive multiple input multiple output (MIMO, multiple input multiple output) and non-orthogonal multiple access (NOMA, non-orthogonal multiple access) technologies can significantly improve the system capacity of the 5G network. and data rate. Although the satellite-ground integrated network has very valuable spectrum resources, part of the mi...
