介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据(The introduction was done with the principle of the QPSK modulation and demodulation in digital communications, a script was written by using Matlab program to carry out a simulation of the QPSK communication system ,which contains the concrete realization of transmit and receive process. The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise, spectral analysis of each module is also done, the results obtained with theoretical results in the main, which provides an effective frame of reference for understanding the performance of QPSK systems, and the practical application in the system to make further designed.)

建立一种可以区分输入图形的形态学算法，算法的输入是这三种图形的一种（这三个图形是对湖、湾、路段的图像细化后的结果），输出是对这三种图形的识别。假设这三种图形都是1个像素宽且完全连通的，然而它们出现的方向可以是任意的。 (Graphics can be imported to create a distinction between the morphological algorithm, algorithm input is a three graphics (which is three graphics Lake, Bay, after the section of the results of image thinning), the output is on these three graphics recognition. Assume that these three are one pixel wide graphic and fully connected, but they appear to be any direction.)

说明：  自适应滤波器原理,一本比较新的书，主要就滤波问题与三种基本估计 进行研究(Adaptive filter theory, a relatively new books, mainly on the filter is estimated with the three basic research)
