不考虑多径干扰时在高斯白噪声和瑞利衰落信道条件下QPSK的调制解调过程， 并采用准分析法完成误码性能的计算。仿真过程包括仿真信号产成，滤波器设置，QPSK调制，加入高斯白噪声，通过锐利信道衰落，QPSK解调，误码率计算等几部分(Not consider multi-path interference at the white Gaussian noise and Rayleigh fading channel under the conditions of the QPSK modulation and demodulation process and the use of quasi-analysis method to complete the calculation of BER. The simulation process includes the middle class into a simulation signal, filter settings, QPSK modulation, by adding Gaussian white noise, through the sharp decline in channel, QPSK demodulation, bit error rate calculation and other parts)

C++大作业，编写一个account类实现基类派生类之间的各种关系。主要用于初学者对于类的理解。(C++ big job, write a class that implements account the various relationships between the base class derived class. The main class for beginners to understand.)

用matlab来做一个三维模型，包括两个部分： 1.长方体 2.很多个半径（远小于长方体边）很小的球体随机分布在长方体中。(Using MATLAB to make a three-dimensional model, including two parts: 1. a rectangular cube with a lot of radius (which is far smaller than the side of a rectangular body) and a small sphere is randomly distributed in a rectangular body.)

轨道设计是飞行器设计专业一门非常重要的专业课。该书是轨道设计的一本经典之作。(Aircraft design professional track design is a very important professional course. The book is designed to track a classic.)

说明：  灰色预测是就灰色系统所做的预测。所谓灰色系统是介于白色系统和黑箱系统之间的过渡系统。其具体的含义是:如果某一系统的全部信息已知为白色系统，全部信息未知为黑箱系统，部分信息已知，部分信息未知，那么这一系统就是灰色系统。(Grey prediction is the prediction of grey system. The so-called grey system is a transitional system between the white system and the black box system. Its concrete meaning is: if all information of a system is known as a white system, all information is unknown as a black box system, some information is known, and some information is unknown, then this system is a grey system.)

类似于MatLab的东东,当然肯定没那么好,但基本的数学运算还是有的(MatLab is similar to the East, of course, is not so sure, but the basic arithmetic or some)
