Embodiment Construction

[0035]Specifically, method 1, a non-orthogonal multiple access energy efficiency optimization method based on spatial modulation in UAV communication, its specific method is:

[0036] Step 1. Provide the network architecture of the remote area without base station coverage for UAV services. The network architecture model is attached figure 1 As shown in , where the downlink communication mode between the UAV and the user is a non-orthogonal access mode, namely NOMA;

[0037] Step 2. Group users according to channel conditions among users, and users in the same group share the same time, frequency and coding resources;

[0038] Step 3. Determine the number of antenna selection bits according to the number of antennas loaded on the UAV. Taking a user group as an example, the UAV divides the downlink information of the users in the group into two parts, namely, antenna selection bits and information transmission bits. The combination of the antenna selection bits of the antenna ...

Abstract

The invention discloses a non-orthogonal multiple access energy efficiency optimization method based on spatial modulation in unmanned aerial vehicle communication, and relates to the technical field of information and communication, in particular to a user power optimal distribution method based on a non-orthogonal multiple access technology, which is used for performing optimal distribution on transmitting power so as to improve the efficiency of system energy. In order to solve the problem of energy limitation of an unmanned aerial vehicle communication scene and the problem of spectrum resource shortage generally generated in the communication scene, the energy efficiency optimization method in a non-orthogonal multiple access technology based on spatial modulation is researched, and a system architecture can be described as follows: mapping a part of bit information to be transmitted to an antenna selection sequence; transmitting the remaining multi-user bit information via power domain superposition. According to the scheme, the power in the NOMA technology is optimally distributed, so that the energy efficiency of the system can be improved.
