A design of telemetry data lossless compression system is proposed based on telemetry data characteristics.In the compression system,wavelet transform is adopted to filter noise which can reduce some redundancy data.Meanwhile,LZW algorithm,a lossless data compression algorithm,is adopted.It can recover no-distortion signal which is required by telemetry data.%在基于遥测数据特点的背景下,提出了一种遥测数据实时无损压缩系统的设计方案。在这个压缩系统中,采用小波变换的方法对数据信号进行去噪预处理,能够有效减少数据量。同时,处理后的数据采用基于字典的LZW无损压缩算法,能够无失真地还原信号,这也正是遥测数据所要求的。
