Abstract
In order to enhance the robustness of massive multiple-input multiple-output millimeter wave communication access network and make open pit mine truck-road collaboration communication more smooth,a robust optimization of mMIMO millimeter wave communication access network for open pit mine truck-road collaboration is proposed.Firstly,a collaborative mMIMO millimeter wave communication access network model and channel model for open-pit mine truck-road are constructed.The digital precoding matrix,array response vectors for transmitting and receiving signals,channel transition matrix,and many other data of the mMIMO millimeter wave communication access network are determined.Based on the parameters of the mMIMO millimeter wave communication access network,precoding techniques are used for optimization.The baseband precoding matrix is designed,and the optimization objective function is constructed.The artificial bee colony algorithm is used to solve the objective function to obtain the optimal precoding matrix and network rate of the mMIMO millimeter wave communication access network.The experimental results show that this method can significantly improve the spectral efficiency and network reachable speed of mMIMO millimeter wave communication access network,with improvements of 15 bit/s·Hz and 25 bit/s·Hz respectively compared to the unoptimized network.Data transmission in an interference environment only resulted in a data loss of 0.5 MB when the data transmission volume was 107 MB,while no other data was lost.关键词
