比较BLAST_STBC_STTC三种空时编码方式性能(Comparison BLAST_STBC_STTC performance of three space-time coding)

Snake Game . This classic snake game is designed in matlab

该代码实现了“大津法”，也就是最大类间方差算法，完全由本人自己编写，结果很好。(The code of the " Otsu method" , which is the Otsu algorithm, written entirely by my own, good results.)

matlab的随机过程仿真实现，包含泊松过程，指数分布，高斯分布等(matlab random process simulation to achieve, including the Poisson process, exponential distribution, Gaussian distribution)

Framing Pyramid的源码。将图片分解成多分辨率的LP(Framing the source. Photo will be transformed into a multi-resolution LP)

实现了PWM整流的功能，并网闭环控制，稳定直流电压。(The function of PWM rectifier is realized, and the closed loop control is connected to the grid, and the DC voltage is stabilized.)

MATLAB程序—一PCM。对PCM编码进行了详细的仿真，效果较好。(MATLAB program- a PCM. PCM coding for a detailed simulation better.)

Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD. They are increasingly replacing conventional communication forms and obtaining extensively applications in modern military and commercial communication systems, for example, CDMA communication system, GPS , measuring and control system, satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS electronic counter technique becomes a big problem to solve in electronic warfare domain. DSSS electronic counter technique including blind detection, blind parameter estimation and spreading sequences estimation. For the issue of DSSS electronic counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian noise (AWGN), the main research content in this dissertation as follow.
