Embodiment

[0103] The illustrations provided in the following examples and the setting of specific parameter values ​​in the model are mainly to illustrate the basic idea of ​​the present invention and to simulate and verify the present invention. In specific application environments, appropriate adjustments can be made depending on actual scenarios and requirements.

[0104] The present invention is oriented to the wireless energy-carrying communication scenario of the mode division multiple access technology, in which both the transmitter and the receiver are equipped with a single antenna. The effectiveness of the proposed method is proved by simulation: (1) The convergence performance of the algorithm under different learning rates is compared; (2) As the user's receiving energy demand changes, the total transmission power of the transmitter changes with different algorithms. Here, the proposed Q-learning algorithm based on constrained Markov process is compared with the DBN algorithm...

Abstract

The invention discloses a resource allocation method for a wireless energy-carrying downlink communication scene of a mode division multiple access technology. By proposing a Q learning algorithm based on a constrained Markov process, the problem of minimizing the total transmission power of a transmitting end on the premise of ensuring the service quality of all users is solved, wherein the proposed user service quality comprises the minimum energy requirement and the minimum data rate requirement received by the users. Through verification, the proposed resource allocation strategy can obviously reduce the total transmission power of the transmitting end.

Description

【Technical field】 [0001] The invention belongs to the field of wireless energy-carrying communication, and in particular relates to a resource allocation method in a wireless energy-carrying downlink communication scenario oriented to mode division multiple access technology. 【Background technique】 [0002] Wireless energy-carrying communication technology is a new type of wireless communication, which combines wireless energy transmission and wireless signal transmission to transmit energy while realizing reliable information interaction. With the rapid development of wireless energy-carrying communication technology, many disadvantages of traditional power supply methods, such as easy aging of wires and difficulty in replacing batteries in time, have been resolved. However, it is still challenging to solve the problems of energy saving and spectrum utilization in wireless portable energy communication technology. [0003] In addition, non-orthogonal multiple access techno...
