On the basis of direct modelling method by using extended Kalman filter, a new method combining extended Kalman filter with adaptive extended Kalman filter is presented to model gyro drift directly from rotate angle of turntable. Extended Kalman filter has great estimation error, what is more, may be divergent if the model and noise statistic are not accurate or wrong. The new method solves the problem of general extended Kalman filter by using fictious noise with timevarying statistic to compensate the linearized model error of extended Kalman filter. The parameter estimators of single-axis and double-axis servo test are designed from it.

The power variation of the targeted harmonic signal and harmonic suppression ratio were calculated and evaluated. The theoretical caculations and simulated results suggest that power variation can be maintained within 1 dB with dc bias drift less than 5% and the harmonic suppression ratio is stable in the SSB RoF link.
理论计算和仿真结果表明,偏置漂移会使目标信号的功率抖动增大,但当偏置漂移量小于5%时,功率抖动小于1 dB,而谐波抑制比保持稳定;分析了与非理想光电调制器啁啾相关的有限消光比和双臂驱动不平衡度对RoF链路性能的影响,有限消光比会增加目标信号的功率抖动并降低谐波抑制比,而通过优化调制器的双臂驱动不平衡度可以提高单边带调制RoF链路性能。

These data are incompatible with the excursion scenario unless (1) carbonates deposited during a negative δ13C excursion are more susceptible to later δ18O metamorphic alteration in proportion to their negative δ13C value, or (2)δ18O of sea water decreases as δ13C of sea water decreases to produce an array that fortuitously resembles the Cenozoic lithification domain Fig.
这些数据与想象的同位素漂移情况不一致,有两个因素应当考虑在内。1。碳酸盐在δ13C存在负值漂移时沉积更加容易受到后期δ18O变质交代作用的影响,这种影响与δ13C成比例。2。海水δ18O与δ13C的同步减少使得数据出现在图表上的近似新生代成岩作用区域,这种情况属于偶然情况。
