Research on the energy consumption of V-MIMO-OFDM system underground coal mines

In order to make sure that the Wireless Sensor Networks can transmit signals efficiently and reliably in uneven, heterogeneous and limited space, the V-MIMO-OFDM mode is used underground coal mines. It allows the nodes equipped with single antenna to process information and transmit collaboratively, so multi-path fading can be resisted efficiently. The energy consumption of SISO, V-MIMO and V-MIMO-OFDM system is studied in this paper. It can be seen from the energy consumption curve that the V-MIMO system can reduce the energy consumption. In a short communication distance, the energy consumption of the V-MIMO system is more than the SISO. But over a certain distance, it is quite the opposite. The V-MIMO-OFDM system further shortens the communication distance. Therefore, the adoption of V-MIMO-OFDM system underground coal mines can greatly reduce the bit error rate and energy consumption. energy consumption.
