基于提升小波的多路径效应减少方法

The Method for Reducing Multi-path Effects Based on Lifting Wavelets

数据后处理技术是解决高精度定位多路径效应的一个有效办法,而基于小波分析的多路径提取和消除技术是其中的一种正在发展中的有效手段之一。提出了一种基于提升小波技术的多路径高频噪声的消除方法,实验证实了该种方法是有效的,同时也证明了该方法实现的简单性和计算的高效率。

The data post-processing technique is an effective method to solve multi-path effect in the highly accurate positioning with the global positioning system （GPS）. And the method of extraction and reduction of multi-path effect based on the wavelet analysis is one of effective ongoing methods. A new method for eliminating the multi-path high frequency noisy based on the wavelet technique is put forward in the paper and the experimental results indicate that the method is very effective, and meanwhile, it proves the simplification of the method realization and the high efficiency of computation.
