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 combined multi-relay selection and time slot resource configuration method for a large-scale MIMO system. According to the method, the advantages of a quantum optimization mechanism and a termite swarm optimization mechanism are combined, the complex hybrid optimization problem of multi-relay selection and time slot resource configuration of the Massive MIMO system is solved by using the quantum termite swarm optimization method, and the method has the advantages of high search speed and high global search capability. According to the invention, a wireless energy collection technology is combined; the energy consumption in the information transmission process of the Massive MIMO cooperative communication system can be obviously reduced; The user terminal and theinterference relay respectively send the interference signal to the stealer to reduce the signal to interference plus noise ratio of the stealer, so that the confidentiality capacity of the Massive MIMO system can be effectively improved, and the safety and the reliability of the communication system are ensured.

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 ...
