Abstract:

In order to meet the data transmission requirements of massive multiple input multiple output (MIMO) systems and reduce the energy consumption of system, an intelligent antenna selection and power allocation method based on quantum chemical reaction optimization is proposed. According to the users' transmission requirements in different periods of massive MIMO systems, the intelligent antenna selection and power allocation model is established, then the maximum energy efficiency equation is derived. To effectively tackle the nonlinear, multi-constrained hybrid optimization problem, a quantum chemical reaction optimization algorithm is designed to obtain the optimal antenna selection and power allocation scheme by combining the advantages of quantum computation and chemical reaction optimization mechanism. Simulation results show that the proposed intelligent antenna selection and power distribution method can meet the transmission requirements of users in real time and significantly improve the system energy efficiency. Compared with existing intelligent algorithms and allocation strategies, the proposed method can achieve the highest system energy efficiency in different simu-lation scenarios.

Key words: massive multiple input multiple output (MIMO), antenna selection, power allocation, quantum chemical reaction optimization
