摘    要:
本成功地将小波变换的多尺寸信号分解(MRSD)方法用于一维核磁共振(NMR)信号的数据压缩。将一幅由32768个数据点构成的NMR谱图压缩至512个数据点,仍能在均方差很小(2.7769×10^-4)的情况下很好地重建原始谱图。

关 键 词:数据压缩  小波变换  核磁共振谱

Abstract:
The multiresolution signal decomposition (MRSD) algorithm based on wavelet transform was applied to the compression of 1-D NMR spectra. A NMR spectrum which was composed of 32768 data points was investigated and the spectrum can be completely reconstructed with the residual square deviation (RSD) being as small as 2.7769 x 10(-4) when the spectrum was compressed to 512 data points. The relationship among the RSD and the different wavelet function, number of decomposiion and the compression ratio was also discussed.
Keywords:Data compression   Wavelet transform   NMR spectra
