| 摘 要： | 为了解决嵌入武GPS车载系统存储空间小、GPS定位数据量大的矛盾，根据GPS定位数据的特点，提出用动态Huffman算法对GPS信号进行压缩。该算法是一种Huffinan算法的基础上改进的算法，为车载系统节省了大量的存储资源。除此之外，也缩短了GSM信道的占用时间，缓解了向控制调度中心上传数据的压力。

| Abstract: | For solve embedded GPS car year systematic memory space little,GPS amount of datum orientated heavy contradiction,orient the characteristic of the data according to GPS,propose compressing GPS signal in dynamic huffman algorithm.Algorithm this one huffman improved algorithm at the foundation of a lgorithm,savea large number of memory resources systematically in year for the car.In addition,it shortens time holding of GSM channel,alleviate to control dispatcher in the cen-ter upload pressure of datum greatly. |
