| Abstract: | It elaborates the importance of cycle slip detection and analysis the advantage of multi-wavelets in signal processing than single wavelets.Based on this,using the relationship model of the maxima value of multi-wavelet transform and the signal singularity,it writes specific steps of multi-wavelet in GPS cycle slip detection.Finally,with the experiment of GPS double difference observation,the result shows the effectiveness of the multi-wavelet transform in GPS phase observations of cycle slip detection. |
