摘要
本文采用按系数不变法设计的线性预测器与Huffman编码，实现了对海洋地球物理勘探反射波和声波测井信号的快速压缩。该方法不仅具有实现简单、运算速度快等特点，而且在不考虑次要波形畸变的情况下，可以大大提高数据压缩比。实验证明，此法用于压缩地球物理勘探数据，可以获得较高的经济效益。
Fast compression of marine seismic reflection and acoustic log signals can be achieved by using both linear predictor designed in the coefficientcainvariable criterion and Huffman coding. The method is characterized by easy performance,fast computation,and higher compression ratio that occurs when inconsiderable waveform distortion is negIected here. The experiment says that the method results in good economical benefit when it is used in geophysical data compression.
