QPSK

以前编的PID程序，关于模糊PID控制方面的，有需要的可以学习下。(PID process previously compiled on fuzzy PID control, and there is a need to learn next.)

有關於語音辨識的檔案，應用於matlab語言(about speech recognization imply in matlab)

使用最小二乘法对任意位置的椭圆进行数据拟合的程序，使用全部的边缘点集。(Anywhere using the least squares method for data fitting ellipse, the use of all of the edge point set.)

Finite Volume Method 流体仿真代码 利用TDMA算法计算二维矩阵 从而计算出二位场内各点的性质 可以通过修改步长和网格大小实现算法研究(A computational fluid dynamics code for determine the property of a two-dimensional plate by using Finite Volume Method. Grid size and time step are free to change in this code.)

this is the star cascade program. it is very useful for beginer

fdtd-finite difference time domain method

Total gradient method extremum If using MATLAB is not difficult, but with C + + is not very easy.(Total gradient method extremum If using MATLAB is not difficult, but with C++ is not very easy.)

对于数据的丢失用不同的方法进行补缺，并且对不同的补缺方法进行了比较(Filled, for the loss of data in different ways, and a comparison of different methods to fill)

说明：  用matlab实现的曼彻斯特编码。50 占空比（可调）。绘制时域波形和频域功率谱密度。结果跟北邮的郭文斌的通信原理课件上的形状一模一样。(Manchester encoding with a matlab implementation. 50 duty cycle (adjustable). Draw time-domain waveform and frequency domain power spectral density. The results with the Beijing University of Posts and Telecommunications of the GUO of communication theory on the shape of the same courseware.)

超宽带定位系统，较好的一本书，涉及很多方面的内容(Ultra-wideband positioning system, a good book, involving many aspects)
