摘要： 針對現(xiàn)有的通信輻射源個體識別方法中人工提取特征復(fù)雜以及深度學(xué)習(xí)網(wǎng)絡(luò)的識別機(jī)制缺乏清晰解釋的問題，提出了一種基于深度自適應(yīng)小波網(wǎng)絡(luò)(Deep Adaptive Wavelet Network，DAWN)的通信輻射源個體識別方法。首先分析了選擇互調(diào)干擾作為輻射源間個體特征的原因；接著應(yīng)用了可實現(xiàn)提升小波變換的卷積神經(jīng)網(wǎng)絡(luò)結(jié)構(gòu)去提取特征，并在其基礎(chǔ)上設(shè)計出可以同時完成特征提取和識別的DAWN；最后，選擇Oracle數(shù)據(jù)集驗證方法的可行性。實驗結(jié)果表明：利用DAWN對5個通信輻射源個體識別的準(zhǔn)確率為95.5%，并且方法具有良好的抗噪性。

Abstract： Aiming at the problem of the complex artificial features extracted in the existing individual recognition methods of communication radiation sources and the lack of clear interpretation of the recognition mechanism of deep learning networks, an individual recognition method of communication radiation sources based on Deep Adaptive Wavelet Network (DAWN) is proposed. Firstly, the intermodulation interference is analyzed as the reason for individual characteristics between radiation sources. Then, the convolutional neural network structure that can realize lifting wavelet transform is applied to extract features, based on which DAWN can complete feature extraction and recognition at the same time. Finally, Oracle data sets are selected to verify the feasibility of the method. The experimental results show that the accuracy of identification of 5 communication radiation sources by DAWN is 955%, and the method has good antinoise performance.
Key words : specific emitter identification；lifting wavelet transform；depth adaptive wavelet network

隨著物聯(lián)網(wǎng)和通信技術(shù)的發(fā)展，無線設(shè)備呈現(xiàn)出指數(shù)級的增長態(tài)勢，未來海量的敏感機(jī)密數(shù)據(jù)將在無線設(shè)備間傳輸，所以對通信輻射源進(jìn)行個體識別對保證無線通信網(wǎng)絡(luò)中的信息安全有著重要的實際意義。
