说明：  实现了对函数的奇偶分频的频谱分析，DFT什么的，包括了4个基础的信号处理实验代码(To achieve parity of function analysis of frequency spectrum)

当文件的某一行存在某一个字符串时，就删除该文件的那一行，并适应于多文件的批量处理。(When a file on a row exists a string, delete the line of the file, batch processing and is suitable for multiple file.)

干涉测向仪通过测量入射波到达天线阵列中单元天线之间的相位差,决定入射波的入射角(Interferometer by measuring the incident wave direction finder antenna array element antenna reaches the phase difference between the incident angle of incidence of the decision)

CIR plot generation in ICI Cancellation in OFDM systems.

说明：  与连续信号的解调相比，短时突发信号持续时间短，不适用性能良好的反馈环路算法，需要使用前向幵环算法。与一般突发信号相比，短时突发信号没有训练序列、同步头等辅助信息，所有参数需要利用有限的数据估计。与合作通信相比，盲接收信号参数的初始偏差较大，估计范围小的算法不适用。每个突发包的数据有限，解调过程不允许丢失任何符号。(Compared with the demodulation of continuous signal, short burst signal has a shorter duration and is not suitable for the feedback loop algorithm with good performance. Forward loop algorithm is needed.)

home work: PSLR, ISLR

these are the gold codes used in the cdma systems.

基于形态学的图像分割，MATLAB实现，先进行灰度变换。(Image segmentation, morphology based on MATLAB implementation, the first gray-scale transformation. )

说明：  三自由度并联机器人运动学正解，特别针对两转动一移动并联机器人(forward kinematics for a three degrees of freedom parallel robot, especially for parallel robot with two rotations and one translation)

包括分层空时编码，网格空时编码，以及分组空时编码，很全面的matlab仿真程序，gui界面(Including the layered space-time coding, space-time coding grid and the split space-time coding, it is comprehensive matlab simulation program, gui interface)
