| 摘 要： | 按照MOF（the Method of Frame）准则,对原子钟信号进行噪声分离,并应用阿伦方差对基于不同小波字典的噪声分离结果进行评价。试验结果表明,应用余弦（DCT）字典、余弦包（CP）字典、Sym8小波包（WP）字典进行噪声分离后的阿伦方差分别从原始信号的4.5538e-15提高到2.2100e-15,3.3125e-15,8.2848e-16,说明MOF准则下,选取适当的小波字典对原子钟信号进行噪声分离,能够获得很好的稳定度。

| Abstract: | In this study noise in atomic clock signals is separated according to MOF(the Method of Frame) criteria,and the Allan variance is applied to appraise the noise-separation result attained by different wavelet dictionary.It is shown that the Allan variance of the noise-separation results applied DCT dictionary,CP(Cosine Packet) dictionary and WP(Wavelet Packet) dictionary,is improved from the origin of 4.5538e-15 to 2.2100e-15,3.3125e-15 and 8.2848e-16,respectively.Indicate that during the process of separati... |
