This is code for finding position of user. This code uses Kalman filter.

三边测量、质心算法、三点定位法、TOA定位算法等一些算法(Trilateration, centroid algorithm, three-point positioning method, TOA location algorithm and some algorithms)

自相关检测方法是利用信号和噪声在相关域上的差别来构造检测器的。自相关检测是将信号与自身延迟一个时延后的信号作相关处理，或用双通道接收机的输出进行相关，得到扩频信号的自相关函数(Auto-correlation detection method is the use of signal and noise in the relevant field to construct the difference detector. Autocorrelation test is a time delay signal and its delayed signal for correlation, or the output of dual-channel receiver, associated, are spread spectrum signal autocorrelation function)
