    Abstract: PROBLEM TO BE SOLVED: To provide compression and decompression of data, specifically, a method and device for compressing and decompressing signal data.SOLUTION: There is provided a method for compressing signal data including acquiring the signal data, determining a block length of a plurality of data blocks into which the signal data is divided and determining an exponent of the data blocks; forming a mantissa sequence of the data blocks by using the exponent of the data block so as to compress the signal data included in the data block, and forming compressed data blocks by using the block length, exponent, and mantissa sequence of the data blocks. The method for compressing the signal data increases a compression ratio of the signal data by constructing variable-length data blocks adapted to dynamic features of the signal data.

    Abstract translation: 要解决的问题:提供数据的压缩和解压缩,具体地,用于压缩和解压缩信号数据的方法和装置。解决方案:提供了一种用于压缩信号数据的方法,包括获取信号数据,确定多个块的块长度 的信号数据被分割成的数据块,并确定数据块的指数; 通过使用数据块的指数来形成数据块的尾数序列,以压缩数据块中包括的信号数据,并通过使用数据块的块长度,指数和尾数序列来形成压缩数据块。 用于压缩信号数据的方法通过构造适于信号数据的动态特征的可变长度数据块来增加信号数据的压缩比。
