Research and analysis of OSTBC in the mine tunnel

This paper builds three dimensions GBSB tunnel model, and analyses the performance of OSTBC in coal mine underground on the basis. The correlation of MIMO channel is very strong in a tunnel. The capability of OSTBC symbol error and the effect of the channel correlation are analyzed on the assumption that there are multi transmitted antennas and only one received antenna. The simulation results show that OSTBC symbol error rate could be decreased obviously by increasing the number of the transmitted antennas, and that change the placing angle of the antennas could also improve the upper bound of OSTBC symbol error rate.
