Coherent Reception of BPSK transmission

calculate a voice detection.also one can calculate the frequency of his/her voice.

这是一个关于机器人的路径算法（vfh算法）在matlab中的仿真。(This is a robot on the path algorithm (Bureau algorithm) in the Matlab simulation.)

说明：  利用matlab软件编写的格子玻尔兹曼方法模拟的圆柱绕流问题，并实现了可视化(The flow around the cylinder is simulated by lattice Boltzmann method compiled by MATLAB software, and the visualization is realized)

是信号处理的基础，包括调制，解调，信噪比计算，是小学期课程设计的题目，包含特征值与特征向量的提取、训练样本以及最后的识别，加入重复控制，可以动态调节运行环境的参数。

this code show the kalman filter

说明：  统计学的计算的matlab实现，大家可以好好学习学习了(Matlab achieve statistical calculations, we can learn from studying the)

将一张图片嵌入到另一张图片中，并提取出来(LSB 算法)(Embed a picture into another picture, and extracted it (LSB algorithm))

串联模糊PID，搭建模糊PID框架，并与普通PID对比，演示模糊控制特点(Series fuzzy PID, fuzzy PID frame structures and contrast with the ordinary PID, fuzzy control features demo)

宽带数字接收机，英文经典，相比中文版，更加原汁原味(Wideband digital receivers, the English classic, compared to the Chinese version, more authentic)
