小波变换实现地震信号的滤波去噪与压缩

Wavelet Transform Algorithm Applications in Filtering and Compressing the Sampled Seismic Signal

讨论了小波变换的快速算法及其对地震信号小波分析与重构的计算机仿真，从而达到对原始信号的滤波处理和压缩，得出了小波分析能较好地应用于对地震信号的分析中的结论，并为开展对地震信号的现场硬件压缩提供了理论依据。

The fast algorithm of the wavelet transform was discussed We imitated the wavelet decompoition and reconstruction precedures, and the sampled seismic signal was filtered and compressed Then, we drawed a conclusion that wavelet can be well used in analysing the sampled seismic signal This conclusion is the theoretical basis of the onsite hardware compression
