| 摘 要： | 提出一种信号调制识别算法.该算法提取接收信号点的极坐标值作为识别特征,利用基于样本与核的相似性度量动态聚类,对不同调制的信号星座图进行分类而完成信号的调制识别.算法较好地克服了相位估计误差的影响,仿真表明该算法有效.

| Abstract: | This paper proposes a recognition algorithm for digital modulated signals.This scheme picks up polar coordinates of received signal point as characteristic.Based on comparable measure between samples and kernels to cluster observation point of received signals,it utilizes dynamic clustering for constellation classification of different modulated signals and completes the modulation recognition.Computer simulations show its effectiveness on mitigating phase estimation error. |
