Embodiment Construction

[0069] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0070]The present invention designs a joint multi-relay selection and time slot resource allocation method for the quantum termite colony of the Massive MIMO system. This method combines the advantages of the quantum optimization mechanism and the termite colony optimization mechanism, and has the advantages of fast search speed and strong global search ability. The advantages are realized through the following steps: the first step is to establish the Massive MIMO cooperative communication system model; the second step is to initialize the quantum termite colony and system parameters, and the position of the quantum termite is obtained through the measurement rules; the third step is to calculate the position of the quantum termite The fitness value of the quantum termite is obtained to obtain the local optimal position of the quantum termit...

Abstract

The invention relates to a method for joint multi-relay selection and time slot resource allocation of a massive MIMO system. The invention combines the advantages of the quantum optimization mechanism and the termite colony optimization mechanism, and uses the quantum termite colony optimization method to solve the multi-relay of the Massive MIMO system. The complex hybrid optimization problem of selection and slot resource allocation has the advantages of fast search speed and strong global search ability. The present invention combines the wireless energy collection technology, can significantly reduce the energy consumption in the information transmission process of the Massive MIMO cooperative communication system, sends the interference signal to the bug through the user terminal and the interference relay respectively to reduce the signal-to-interference-noise ratio of the bug, and can effectively Improve the confidentiality capacity of the Massive MIMO system to ensure the security and reliability of the communication system.

Description

technical field [0001] The invention relates to a joint multi-relay selection and time slot resource allocation method of a massive MIMO (Massive MIMO) system, and belongs to the key technical field of 5G mobile communication. Background technique [0002] With the rapid development of information technology, mobile communication is promoting social change in an unprecedented way. Compared with 4G networks, 5G networks can meet higher data transmission requirements, have wider wireless communication coverage, better communication quality, and can build a new scene of Internet of Everything. However, with the rapid development of 5G communication, the greenhouse gas emissions and energy consumption caused by mobile communication will become increasingly serious. In order to achieve sustainable development, green communication has become a research hotspot in 5G communication. As one of the key technologies of 5G, Massive MIMO can significantly reduce energy consumption. Its ...
