important aspect in the ASK modulation scheme

The two dimensional LMS program is used to enhanced image contrast by adaptive filtering process, it operates on every fixel through each row and column

说明：  emd分解及其重构,分解成对个IMF，然后进行重构(emd emperical modal decomposition)

time frequency analysis for images

一个雷达回波模拟的matlab程序包,含有在RCS服从卡方分布,瑞利分布,对数正态分布下目标的的雷达散射截面模拟子程序，(Matlab simulation of a radar package, containing the RCS subject to chi-square distribution, Rayleigh distribution, lognormal distribution of the target' s radar cross section simulation subroutine,)

说明：  试编写一程序，要求比较数组ARRAY中的三个16位补码数，并根据比较结果在终端上显示如下信息：1如果三个数都不相等则显示0；2如果三个数有两个不相等则显示1；3如果三个数都相等则显示2。(Try to write a procedure that requires more in the array ARRAY complement of three 16-bit number, and the terminal on the basis of comparative results show the following information: 1 if the three numbers are not equal, display 0 2 if two of three the number of Showing 1 are not equal 3 If three numbers are equal, displays 2.)

星载SAR仿真 可以得到很好的成像效果，大家可以试一试(Simulation of spaceborne SAR imaging results can be very good, we can try)

说明：  fdtd 1d

本matlab函数实现基带信号的成形和眼图的观测，其中眼图的观测函数可以判断码间串扰的强度。(Matlab function of the base-band signal shape and the eye diagram of the observation, the eye diagram of the observation function can determine the strength of intersymbol crosstalk.)

对基带数字通信的位同步过程进行了仿真，采用Gardner算法，没有用插值。符号用SRRC进行脉冲成形，环路滤波器没有用PI回路，是简单的alfa，1-alfa低通滤波，NCO调整也比较简单。(Baseband digital communications for the bit synchronization process of the simulation, using Gardner algorithm, did not use interpolation. Carried out with SRRC pulse shaping symbols, did not use PI loop filter circuit is a simple alfa ,1-alfa low-pass filter, NCO is also relatively simple to adjust.)
