Abstract

The invention discloses a non-orthogonal multiple access communication system based on wireless power transmission. The communication system comprises a multi-antenna energy base station, a plurality of sensor nodes and an information receiver, wherein the energy base station is used for transmitting energy to each sensor node based on an energy beam forming technology; any sensor node is used for sending collected information to the information receiver in a non-orthogonal multiple access manner by using the received energy; and the information receiver is used for receiving and decoding the information collected by each sensor node. With the application of the communication system provided by the embodiment of the invention, the energy allocated to each sensor node by the energy base station is optimized, the energy can be reasonably allocated, a reachable speed from the sensor node to the information receiver is improved, problem complexity is reduced, and performance of the whole communication system is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a non-orthogonal multiple access communication system based on wireless energy transmission. Background technique [0002] In a wireless sensor network, there are a large number of wireless sensor nodes. Battery life is an important factor affecting the normal operation of wireless sensor nodes. In the case of a large number of wireless sensor nodes, it is very cumbersome and costly to replace or recharge the battery. [0003] Currently, wireless energy transfer technology can solve the battery life problem. Wireless energy transfer technology takes advantage of the far-field radiation properties of electromagnetic waves. The wireless sensor nodes can receive radio frequency signals transmitted from the energy base station, and the energy of the energy base station comes from various renewable energy sources, such as solar energy, wind power, water power, etc. [0004]...
