摘要
本文建立了实际工程应用中信号的仿真模型和干扰模型,运用小波变换和数学形态学相融合的方法进行降噪,并将该方法与小波阈值方法、小波模极大值法、数学形态学方法的仿真结果进行对比分析,仿真分析结果发现小波-形态融合方法能够有效的消除噪声且能较好地保留原信号的形态特征。
This paper established the practical engineering application of signal simulation model and interference model, using the wavelet transform and mathematical morphology fusion method for noise reduction, and using the methods of the wavelet threshold method, wavelet modulus maximum method, mathematical morphology method the simulation results were analyzed, the simulation analysis results find wavelet morphological fusion method can effectively the elimination of noise and can preserve the original signal characteristics.
