摘要: 传统调制识别算法是基于高斯白噪声信道的,在复杂信道条件下识别性能明显下降。针对此问题,提出基于抗混淆线性判别分析A-ALDA (Anti-alias Linear Discriminant Analysis)和堆叠稀疏降噪自编码器SSDAE (Stacked Sparse Denoising Autoencoders)的调制识别算法。该算法中,A-ALDA算法将信号累积量特征重构为新的特征,这些特征具有更优的分离性能;将原始特征与新特征输入SSDAE进行分类,SSDAE具有提取关键信息和抗噪声的能力。结果表明,本文算法的识别准确率高于已有的算法;并且在有限信号长度条件下和相位、频率误差干扰情况下,识别准确率均有提高。
