摘要
在研究小波分解算法的基础上,结合遥测信号的变化特性,分析了小波算法在遥测数据处理中虚假趋势排除和信号去噪两方面的应用,并与传统分析方法进行对比,通过仿真结果证明了小波分析方法的有效性。
Combined with the change character of the telemetry signal,this paper studies the wavelet analysis algorithm.The paper also studies the application of wavelet analysis in trend eliminating and signal de-noising.The paper also compared this method with traditional method,and proves the effective of this method through simulation.
