Research of Underground Pipeline Leakage Signal Denoising Based on Adaptive Filtering

研究了自适应滤波算法对地下管道漏水信号的去噪处理,对归一化最小均方(Normal Least Mean Square,NLMS)自适应滤波算法与传统的最小均方(Least Mean Square,LMS)算法进行性能比较,并通过MATLAB仿真验证分析,最终采用DSP芯片TMS320C5402在CCS软件平台上实现了NLMS自适应算法对地下管道漏水信号噪声的滤除.

In this paper the adaptive filtering algorithm for leakage signal noise processing was studied. The performance of LMS algorithm and NLMS algorithm were compared and verified by MATLAB simu-lation.Finally,by using DSP chip TMS320C5402 on CCS Software platform,leakage signal to noise filter was achieved with the NLMS adaptive algorithm.
