PN Codes Correlation Properties

说明：  从地理坐标到笛卡尔直角坐标转换,考虑到不同的椭球投影。(function to calculate the geodetic Earth-fixed coordinates )

说明：  异步电机矢量控制控制的matlab实现,系统采用3个pi调节器(Vector control of induction motor control to achieve matlab)

已知观测数据为A+W(n)，其中A为直流信号，W为复高斯噪声，服从CN（0， ），在统计N次下，计算X的统计平均值 ，求T(x)= 的pdf：p(T(x)|H0)、p(T(x)|H1)。 H0： W H1： A+W (Known observation data A+W (n), where A is the DC signal, W is the complex Gaussian noise, subject CN (0,), N times in the statistics, the calculation of the statistical mean of X, find T (x) = a pdf : p (T (x) | H0), p (T (x) | H1). H0: W H1: A+W)
