说明：  MATLAB的向量矩阵运算，可以了解矩阵和向量在MATLAB中的用法。(MATLAB' s vector matrix operations, matrix and vector can understand the usage in MATLAB.)

科斯塔斯环载波恢复，用来跟踪输入信号的载波频率(carrier recovery by costas loop)

很好的matlab参考书，唯一的缺点是全英文，不过写得很详细(Matlab very good reference book, the only drawback is that the whole English, but very detailed)

说明：  杂波的一个MATLAB仿真，杂波的产生：先生成一个（0，1）分布的随机数r，让后根据poission分布产生杂波的个数n，这n个杂波是服从均匀分布(Clutter a MATLAB simulation, the resulting clutter: a President (0,1) distribution of the random number r, let poission distributed according to the number of clutter have n, that n is subject to a uniformly distributed clutter)

最大似然估计法的matlab实现，及Crammer-lor下界的确定(Maximum likelihood estimation of the matlab implementation, and Crammer-lor to determine the lower bound)

通信中的QPSK相位调制建摸，其中考虑了多径和高斯的影响(Communication QPSK modulation phase modeling, which takes into account the multi-path effects and Gaussian)

基于SIMULINK搭建的并联有源电力滤波器程序，希望大家，相互交流。(SIMULINK-based structures of Shunt Active Power Filter procedures, hope, each other.)

the file contains detection and estimation theroy codes

直接序列扩频源程序,对于研究扩频的朋友十分有益，请大家下载！(the code of DSSS，It s very good for study DSSS)

经PPM调制的超宽带信号经高斯白噪声信道的系统仿真,给出了时域和频域图(Modulated by the PPM UWB signal by Gaussian white noise channel of system simulation, given the time and frequency domain map)
