MATLAB

通信系统仿真用到的源码，关于matlab 的，希望对大家有用 (Source code used in communication system simulation on matlab, and I hope for all of us)

Watermarking matlab code for digital signal processing

直接序列扩频（DS）原理的仿真程序，通过该程序你可以很好地理解直接序列扩频原理。(Direct Sequence Spread Spectrum (DS) The principle of simulation program, through the program you can very well understand the principle of direct sequence spread spectrum.)

维特比算法,信道编码的最大似然译码方法之一.(Viterbi algorithm, channel coding maximum likelihood decoding methods.)

主要用途是对抗多径衰落。由于多径衰落的存在，使得同一个帧由于路径不同，到达用户端的时延有先有后。在相关的频域上的会造成子载波之间的相互干扰，影响 性能。另外，由于有了循环前缀，使得IFFT FFT操作把原来的线性卷积变成循环卷积，大大简化了相应的信号处理复杂度(The main purpose is to fight against multipath fading. Due to the presence of multipath fading, the first after they have the same frame different paths to reach the client delay. Would cause mutual interference between sub-carriers in the frequency domain, affecting performance. In addition, thanks to the cyclic prefix, so IFFT FFT operation to the linear convolution of the original into a circular convolution, greatly simplifying the corresponding signal processing complexity)

matlab编程风格指南，比较系统的讲解了mantlab的编程习惯于编程要素(matlab writing style)

Algorithm for energy detector.

倒立摆控制，可以调整参数自动仿真；图像显示清晰；直观效果；本人调试过，很好用！！(Inverted pendulum control, you can adjust the parameters of automatic simulation; image display is clear; intuitive effect; I debug, very good use!!)

虚拟频谱分析仪。vi可以好好的学习参照设计(Virtual spectrum analyzer. vi)

该程序，应用了蚁群方法完成了对配电网故障恢复功能，得出可操作开关集(The application of ant colony algorithm procedures, the completion of the distribution network fault recovery function, which can be operated switch set )
