Abstract:

In a moving satellite communication system, the precision of the carrier’s disturbance signal detected by the gyro has a direct impact on the precision and the performance of the system. According to the feature of the gyro noise signal, a filtering method which integrates the 3σmodular square threshold and translationinvariantdiscrete wavelet transform (TIDWT) is proposed. The method can effectively eliminate the noise of gyro signals and the distortion produced in the wavelet transform. The simulation and experiment results show that the filtering results are better than the traditional wavelet filtering methods.
