| 摘 要： | 针对常用的卫星通信信号的调制方式识别问题,提出了一种新的自动识别算法.该算法基于统计特性分类原理,通过建立一组统计特征参数,在无需先验信息的条件下,实现对信号调制方式的自动识别.对实际采集数据进行了实验验证,结果表明该算法在低信噪比环境下仍有较高的识别率,简单易用,具有较强的工程可行性和良好的扩展性.

| Abstract: | A recognition algorithm for digital modulations commonly used in satellite communication is presented.Based on a set of statistical features,many digital modulated signals can be recognized through classifying decision without any prior knowledge.This algorithm is verified by some practical sampling data.The experiment results show that the algorithm can work perfectly under a low SNR circumstance and it is feasible and practical. |
