【摘要】 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,本文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。更多还原

【Abstract】 The data post-processing technique is an effective method to solve multipath effect in the highly accurate position- ing with the global positioning system (GPS).And the method of extraction and reduction of multipath effect based on the wavelet analysis is developing to be an effective method.A new method based on the lifting wavelet technique to eliminate the multipath effect is put forward in the paper.Then a practical case is made.The results indicate that the new method is very effective to reduce the multipath effect.It is very simple to realize the method and the method has the merit of highly efficient computation.更多还原
