Abstract

An NOMA wireless information and energy transmission method based on cooperation of a diameter and a relay comprises the steps that firstly, an information source node broadcasts superposed coded signals to a relay node and two users, and the relay node conducts power distribution on received radio frequency signals and achieves energy collection and signal decoding; then, the relay node generatesa new superposed signal, and forwards the new superposed signal to the two users by utilizing the collected energy; diameter transmission and relay transmission are respectively used for the two users to form a received signal orthogonal structure, and expected signals are recovered by adopting linear combination. According to the NOMA wireless information and energy transmission method based oncooperation of the diameter and the relay, the orthogonal structure of diameter transmission and relay transmission is formed by adopting the rotation / reflection matrix, so that the receiver can detect the user signal by adopting linear combination, the complexity of the receiver is effectively reduced, the interruption performance of a system user is effectively improved, and the reliable transmission of the user signal is ensured.

Description

technical field [0001] The present invention relates to a NOMA wireless information and energy transmission method using diameter and relay cooperation, and more specifically, to a NOMA multi-user wireless information and energy transmission using diameter transmission and relay node cooperative transmission, and then using Diameter transmission and relay transmission form the characteristics of an orthogonal structure, and a method of linearly combining at the receiver to recover the desired user signal. Background technique [0002] Due to its ability to provide large-scale heterogeneous wireless communication for the Industrial Internet of Things, non-orthogonal multiple access (NOMA) technology in the power domain has attracted extensive attention from both industry and academia. The NOMA technology in the power domain enables multiple users to share the same time / frequency / code resource by superimposing the signals of multiple users in the power domain. In addition, th...
