Application of MIMO Coil-Array in Underground Magnetic Induction Communication
Magnetic induction (MI) communication is a promising underground wireless communication method with significant advantages. In recent years, many efforts have been made to improve the communication performance of MI, but the MI system has only one resonant frequency and narrow bandwidth. To solve this problem, this paper proposes a magnetic induction multi-input and multi-output (MI-MIMO) antenna array, which increases the bandwidth of magnetic induction communication by means of multi-channels, and a coil deployment method is proposed to reduce crosstalk in MIMO communication by deploying two orthogonal coils in the transceiver node. Based on the established model, the path loss and channel capacity of MI-MIMO are obtained through numerical and simulation analysis, and the power allocation method to optimize the capacity of MI-MIMO is studied. Finally, the advantages of MI-MIMO are proved by comparing with ordinary MI..
