CVSD，连续可变斜率增量调制，用MATLAB写的-CVSD, continuously variable slope delta modulation, written with MATLAB

针对传统线性调频(LFM)信号参数估计算法中复杂的搜索和计算问题，提出了一种不需要参数搜索的快速 LFM信号参数估计算法。该算法先用希尔伯特变换估计LFM信号瞬时相位，再用二次相位函数拟合LFM信号瞬 时相位从而得到初始频率和调频斜率的估计-The traditional linear frequency modulation (LFM) signal parameter estimation algorithms and computational complexity of th

目前国内外最好的计步器代码，带传感器灵敏度调节，根据斜率判断步伐踩点，精确记步，一直在研究计步器算法,这个是最好的了,难得分享给大家-Currently the best domestic pedometer code with sensor sensitivity adjustment, determine the slope of the pace of the Capitol, accurate step counter, pedometer has been studying the a
