摘要:

       结合海水中总有机碳测定的信号除噪问题,对基于小波变换的信号除噪基本原理和方法进行了研究。算法由Visual C++编制完成,通过对采集的信号进行分解,去除其中的高频信号,最后再重构回信号,实现了一维小波的信号处理。实验证明,该算法简捷有效,能达到降低干扰的目的。

关键词: 小波变换, 去噪, VC++

Abstract:

        This paper presents a wavelet transform based signal noise reduction algorithm for the signal denoising problem of the determination of seawater total organic carbon. This Visual C++ implemented algorithm decomposes the collected signal, removes the high frequency signal components and reconstructs back to the noise reduction signal. Experiments show that the algorithm is simple and effective and can achieve good noise reduction effect.

Key words: wavelet transform, denoising, VC++
