For further analysis,four pairs of simulated DD system
errors with respect to the practical experimental data are
investigated (details of the experiment will be given in
next section).A standard deviation of 0.05 cycle are
added to this data and analyzed,and the trend extracted
results are given in Figure 6.Only the analysis on the
simulated PRN21-17 DD systematic errors are given here
due to space limitations.The residual series of the three
models are given in Figure 7.EMD results and wavelet
trend extraction of imf1 are shown in Figures 8 and 9
respectively.Table 1 gives the quantitative evaluation
quantities for the different models,which shows that the
EMD-Wavelet model has the highest SNR and lowest
RMSE with respect to the four pairs of simulated DD
series.

进一步分析,四对与实际实验数据进行了模拟DD systemerrors（实验的细节将在未来的部分）.0.05周期加入这个数据分析的标准偏差,和趋势extractedresults给出如图6.只有在模拟prn21-17 DD系统误差进行了分析heredue空间的限制.三种模型的残差序列在图7.EMD结果和IMF1 wavelettrend提取在图8和图9所示.表1给出了不同模型的定量evaluationquantities,这表明theemd小波模型具有最高的信噪比和lowestrmse相对于模拟ddseries四对.
