Abstract: In order to solve the frequent communication obstacle problem in multiple-input and multiple-output (MIMO) system communication caused by routing conflicts, it is necessary to quickly locate the optimal nodes for communication, so a fast optimal node locating algorithm for MIMO system communication based on link balance control is proposed in this paper. In this algorithm, a MIMO system communication channel model is constructed through the link balance control method, and interference features of signals are separated by analyzing the spectrum of communication signals based on the model. Simulation results show that this algorithm can provide 100% accuracy in optimal node locating under signal-to-noise ratio of 80 dB, an average improvement of 13.8% over that in traditional algorithms. The results show that our algorithm can provide high accuracy in locating the optimal nodes for communication, and can ensure high locating efficiency, which effectively improves the communication transmission quality of MIMO system.
