精密单点定位:精密单点定位程序，对于电离层、对流层、双频观测值改正等有较强的改正作用(very good!)

说明：  作为初学者的典范,但是程序有很些许错误，还希望高手指点，特别是运行时，每次出的结果不一样，更希望高手指点！(this project is just so so ,it can be used to study by the first learner!certainly ,there are some misstakes, but i can not find it ,because my level is just so so ,i hope you can correcting me !thank you very much !if you correct my project ,pleased send email to hljdx.wuyou@163.com ,thanks! i found my project ,there are so many results when i run ,i do not know why?)

说明：  里面有不少MATLAB学习课件,对新手很有帮助。(there are many study matiarial)

用于图像分割的数学形态学分水岭算法的matlab实现。(Matlab code of Watershed algorithm for image segmentation.)

《MATLAB信号处理超级学习手册》随书光盘， 《MATLAB信号处理超级学习手册》以MATLAB R2013a版本为基础，系统地讨论了数字信号处理的基本理论、基本分析方法、基本算法和设计方法，涉及了数字信号处理的各个方面，是一本比较全面的信号处理参考书。( MATLAB Signal Processing super study manual In MATLAB R2013a version of the basis, the system discussed in the basic theory of digital signal processing, the basic analysis methods, basic algorithms and design method involves all aspects of digital signal processing, it is a more comprehensive signal processing reference.)

实现随机信号序列的QPSK调制和相干解调，观察信号的星座图，计算误比特率和误码率。(this code is designed for the signal s QPSK modulation and demodulation exactly. Meanwhile, the BER and SER were estimated and drawed.)
