在对一些变步长LMS算法分析的基础上，提出了步长因子 (n)与误差信号e(n)之间一种新的非线性函数关系-In a number of variable step size LMS algorithm based on the analysis, put forward a step length factor (n) and error signal e (n) between the non-linear function of a new relationship

A FFT-based partial matched filter (PMF) acquisition threshold setting method for fast GPS acquisition is presented. Normal distribution and numerical fitting technique instead of real decision variable (DV) distribution are used in derivatio
