Study on modeling method of leaky coaxial cable network channel in underground coal mine

To study the high speed data communication and fault diagnosis of the leaky coaxial cable (leaky cable) network in underground coal mine, a method based on multipath propagation for establishing the leaky cable network channel model is proposed. The multipath propagation of the leaky cable network and the transfer characteristic of the leaky cable are analyzed. The transfer function between the network terminals is solved based on the multipath propagation, and the channel model of the leaky cable network is established. The results have been verified successfully by comparing the measurement results with simulations based on the model, which is obvious that simulation and measurement differ only in minor details.
