【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第二代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】 Data post-processing technique is an effective method to solve multipath effects in high accurate positioning with GPS.And the method of extraction and reduction of multipath effects based on wavelet analysis is a good way which is now in development.This paper presents a new method which is based on the second generation of wavelet technique to eliminate the multipath effects.Then,a case study is made.The results indicate that this new method is very effective to reduce the multipath effects,and it could be very simple to carry out.Besides,this method has been proved of highly efficient computation.更多还原
