说明：  求模极大值的程序MATLIB源码,可以用此方法来判断时间序列的奇异点,并根据它来恢复信号.(modulus maxima for the procedure MATLIB source, you can use this method to determine the time sequence of singular point, and according to restore its signal.)

说明：  matlab 实现汽车悬架分析，四分之一、二分之一，整车悬架悬架(matlab achieve vehicle suspension analysis, a quarter, half, vehicle suspension suspension)

Orbit determination and control source Matlab code

M-file uses random data which BPSK modulates a carrier to configure a BPSK UWB transmitter. The receiver demodulates the BPSK UWB carrier and the data is recovered

这是一本数字信号处理的经典书籍，本人好不容易找到的，和大家分享，希望能帮到大家~~(This is a digital signal processing of the classic books, I finally found, and share, hoping to help you ~ ~)

基于一阶AR模型u(n)=0.99u(n-1)+v(n),白噪声方差0.93627.步长0.05.分别使用M=2和M=3抽头的滤波器，用LMS算法实现u(n)的线性预测估计。并附仿真图已被参考。(Based on a first-order AR model u (n) = 0.99u (n-1) the+v (n), the white noise variance 0.93627 step 0.05. Respectively with M = 2 and M = 3-tap filter, with the LMS algorithm u (n) of the linear prediction estimates. Along with simulation diagram reference.)
