Because communication underground coal mine is difficulty, this paper analyzed the underground power line noise, and indicated that we can design the adaptive filter based on the adaptive theory and deal with the channel noise. Experiments show that, through the adoption of improved Adaptive Noise Canceling technology and DSP system we can achieve to remove the noisy and gain pure signal.
