利用磁力计进行姿态估计的程序，用到了欧拉角法和四元数的方法(The use of magnetometers for attitude estimation procedures used in the Euler angle method and quaternion method)

powell method minimum search

这是一个matlab的程序包，里面都是一些经典和常用的例子，有完整的代码。(this is a package of matlab code, in which there are lots of classic and useful examples with whole code.)

一个应用psk调制的通信系统matlab仿真，应用matlab中的图形操作界面simulink，psk是现在应用最广的调制方式，有很大的参考价值(An application psk modulation matlab communication system simulation, application of the graphical interface matlab simulink, psk is now the most widely used modulation, have great reference value)

使用Waxmans算法产生一个随机网络(generate a random network by the well-known Waxmans algorithm)

说明：  5、绘制散点图。 对发射和接收信号利用scatterplot函数可显示信号星座图的样子及噪声对信号造成的失真程度。在该图中，横轴代表了信号的同相分量而纵轴代表了正交分量。下面的代码还利用了 对接收信号利用modem.deqammod对象的demodulate方法进行解调。解调结果为包含0到15之间整数的列向量。 (5, draw a scatter plot. The transmitted and received signals can be displayed using a function of the degree of distortion scatterplot like and noise signals caused by the signal constellation of FIG. In this figure, the horizontal axis represents the in-phase component signal and the vertical axis represents the quadrature component. The following code is also used to demodulate the received signal using the method of demodulating modem.deqammod object. Demodulation result is an integer from 0 to 15 comprising a column vector.)

曲线波变换用于图像去噪可以很好的解决物体沿曲线边缘的特性，本算法基于USFFFT，可以更高效的进行去噪(Curvelet transform for image denoising can solve problems well along the curve edge features, the algorithm based on USFFFT, can be more efficient denoising)

a book about wifi. very informative

说明：  本文件夹包含的是针对电话交换系统的C51程序源代码，包含了电话串口之间的通信功能，以及控制回铃音的程序源代码(This folder contains the telephone exchange system for the C51 source code, including a telephone communication between the serial port, and control ring back tone of the program source code)
