Abstract

The invention discloses a non-orthogonal multiple access network security transmission method based on the ARQ protocol. The wireless network includes: a sending node S, N users i, i∈{1,2,...,N}, and An eavesdropping node e, the sending node selects user m and user n to send signal x according to channel conditions, and user m and n demodulate their respective destination signals from signal x, wherein the user m and user n respectively use automatic re- The transmission request technology communicates with the sending node, and the signal power decreases successively for each retransmission. The beneficial effect of implementing the method of the present invention is to enhance communication reliability and reduce information leakage, especially in the case of low power; and it has low requirements on hardware resources, simple operation, easy engineering application, and can be applied to large-scale Internet of Things scenarios.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an ARQ protocol-based non-orthogonal multiple access network security transmission method. Background technique [0002] With the development of the Internet of Things technology, the concept of the Internet of Everything has received widespread attention in the industry. In the information transmission of the Internet of Things, on the one hand, it is a major challenge to realize massive connections under limited communication resources; on the other hand, low-cost communication nodes occupy an important proportion. Due to the limitation of equipment cost, these communication nodes are difficult to complete Computational tasks and channel estimation, therefore, achieving reliable communication under the constraints of equipment cost is another big challenge. Non-orthogonal Multiple Access (NOMA) technology, the basic principle of which is that the transmitting en...
