| 摘 要： | 在分析了多普勒信号的特性及语音信号的区别后，采用自适应离散余弦变换算法对多普勒信号进行了压缩编码，在中等编码速率下得到了较好的压缩编码效果。文中提出了相关－自适应离散余弦变换（C－ADCT）压缩编码算法，改进算法提高了自适应离散余弦变换算法的抗噪性能。

| Abstract: | In this paper,after the characteristic of doppler signal and the difference with voice signal are analyzed,the algorithm of ADCT is used to compress the doppler signal. At a medium encoding rate,this algorithm can give a good compression encoding performance. The correlation ADCT algorithm is presented in this paper,which improves the anti noise performance of ADCT. |
