To address the issue of massive data in distributed acoustic sensing system, we proposed using the ultra-low sampling resolution and undersampling techniques to reduce the data volume last year. However, the fading noise of the 1-bit undersampled signal becomes difficult to be completely removed with conventional denoising methods. In this paper, we proposed an integrated fading suppression algorithm to solve this problem. Experimental results show that the proposed approach can completely eliminate the fading noise of the 1-bit undersampled signal, while the vibration signal-to-noise ratio is also enhanced by 7.72 dB.
