摘　　要：将提升小波用于GPS(Global Positioning System)周跳探测.提升算法相对于传统的第一代小波算法而言,是一种更为快速有效的小波变换实现方法.它不依赖于傅里叶变换,具有计算速度快,计算时无需额外的存储开销,计算方法更简单等优点.仿真结果表明,提升小波不仅能够准确地探测周跳,而且比传统小波计算方法更简单,计算速度更快.Lifting wavelet was being applied in the detection of cycle slip.Lifting arithmetic is a faster and more effective technique compared to first generation traditional wavelet.Independence of Fourier transformation,lifting wavelet has the virtue of faster computation rate,simpler calculation means and does not require additional storage.Simulation has demonstrated the effectiveness,speed and accuracy of lifting wavelet in cycle slip detection.
