semblance analysis in matlab

BER SNR plot in rayleigh channel with maximal ratio combining technique for MIMO

LS-estimation, yule walker equation, levinson durbin algorithm

产生脉冲线性调频信号，去除暂态点，加噪声之后进行动目标检测(Pulse chirp signal, remove the transient points, plus noise after moving target detection)

用matlab仿真了电磁波在地面传播时的反射，传播特性。(Matlab simulation with reflection, propagation characteristics of electromagnetic waves propagation in the ground.)

It is matlab code for object detection

针对提出的故障信号，利用awgn加噪，对其进行小波软硬阈值降噪，提出一种改进阈值，利用五种自适应阈值函数sqtwolog、rigrsure、heursure、minimaxi和ddencmp中阈值选取原则，对软阈值、硬阈值和改进阈值进行降噪效果对比。(In view of the proposed fault signal, the wavelet soft and hard threshold de-noising is carried out by AWGN adding noise, and an improved threshold is proposed. The threshold selection principle of five adaptive threshold functions, sqtwolog, rigrsure, heursure, minimaxi and ddencmp, is used to compare the soft threshold, hard threshold and threshold value.)

利用matlab控制3维仿真软件sonnet的工具箱，里面包含了详细的试用说明PDF，还有一个微带天线的例子，使得对天线的设计变得简单。(Using matlab to control 3-D simulation software sonnet Toolbox, which contains a detailed description of the trial PDF, there is a microstrip antenna example, makes the simple antenna design.)
