Problems solved by technology

[0004] The existing energy allocation scheme under the model of maximizing the total information rate of users, it is found that under this model, the information rate of users farther away from the relay is significantly smaller than that of users closer to the relay, that is, the phenomenon of "near and far" is obvious, and it cannot be guaranteed Fairness of user information rate in multi-user relay system

Abstract

The invention discloses an energy allocation method based on maximization of user public information rate, based on a multi-user relay system model, to ensure that the information rate of each user in the system is equal and maximized, and to ensure user information in the multi-user relay system Rate fairness.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and more specifically relates to an energy allocation method based on maximizing user public information rate. Background technique [0002] Relay technology can extend the coverage of communication, increase the capacity of the system and improve the quality of service for users. As a forwarding node in the communication system, the relay has the functions of receiving and forwarding. The receiving strategy of the relay receiver has an important impact on the performance of the system. [0003] In a multi-user relay system, due to various factors such as geographic location, the distances between user receivers and relays cannot all be the same. There is fading in the process of signal transmission, and the farther the transmission distance is, the more serious the fading will be. [0004] The existing energy allocation scheme under the model of maximizing the total info...
