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.
