对图像进行逐点计算，并且取最大值和最小值的差值作为该点新的灰度值。 在区别边缘点和非边缘点时，首先确定一个阈值T，若图像中像素点的新 值大于该门限值，则可以初步确定为边缘点，小于T的新值被判断为非边缘点.(Image point by point basis, and taking the maximum and minimum points of difference as the new gray value. Edge in the difference between point and non-edge point, first determine a threshold T, if the image of the new pixel value is greater than the threshold, you can initially identified as the edge point, the new value is less than T have been judged as non-edge point.)

说明：  ofdm的同步有关的参考文献，讲述了各种同步的方法。(ofdm synchronization related references about a variety of synchronization methods.)

讲解了一些最常用的例子并加以说明，从而更深入的了解(Explain some of the most common example is to illustrate to a better understanding of)

关于卡尔曼滤波的例子以及工具箱，经测试可以使用(Kalman filter on the example and tool kit, the test could be used)

This is a simple Simulink model for digital PAM in AWGN channels.

采用延时相乘法实现GPS信号的捕获，模拟产生三颗卫星的信号，然后通过延时相乘并进行频谱分析来得到伪码和多普勒频移(And delay phase multiplication analog GPS signal acquisition )

对最基础卡尔曼滤波器的仿真，对于初学者了解卡尔曼滤波器工作原理有一定参考价值(Simulation on the most basic kalman filter, for beginners to understand working principle of the kalman filter has a certain reference value)

说明：  S变换是较新的时频分析工具，甩在低频段有较宽的的时间窗，以获得较高的频率分辨率；而在高频段时间窗窄，以获得较高的时间分辨率。这里给出了ST和GST（广义S变换）的函数。(S transform is a relatively new time-frequency analysis tool, left in the low frequency band has a wide time window in order to obtain higher frequency resolution and in high-frequency narrow time window in order to obtain higher temporal resolution. Here are given ST and GST (generalized S transform) function.)
