Abstract: 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.
