基于自适应子带频谱熵的稳健性语音端点检测(Based on adaptive sub-band spectral entropy of the robustness of Speech Endpoint Detection)

遗传算法是兼职编码求函数的极大值程序，比较详细。(A function or part-time coding genetic algorithm (ga) is a great value program, more detail.)

for cross entropy implementation

数字语音信号处理端点检测MATLAB仿真(Endpoint detection digital signal processing MATLAB simulation )

This is code to simulation of AM, FM, PSK, QAM modulation

由入门到精通吃透PID２．０版-焦作华润白志刚(Thorough understanding PID2.0 by the entry to the master version- Jiaozuo Resources Bai Zhigang)

matlab中文说明，对于英语基础不行的人是一个很好的帮助。(matlab Chinese explanation, not for the foundation in English is a good help.)

说明：  自己做的两相混合式步进电机细分驱动控制，已经闭环成功，效果还不错(Self-made two-phase hybrid stepping motor subdivision drive control, has been closed-loop success, the effect is good.)

这是用SIMULINK的S-FUNCTION方式编写的系统仿真代码，系统是基于4G网络的核心技术空时分组编码的MIMO-OFDM通信系统的，涉及到空间分集、时间分集和频率分集的有机结合，包括QPSK调制解调、IFFT调制、控制编解码、基于训练符号的信道估计等通信模块。包括main_STBC_MIMO_OFDM和training_symbol两个M文件和一个DOC文件，对各部分的都有详细的代码和注释。(It is used SIMULINK the S-FUNCTION approach to the preparation of the system simulation code, the system is based on the 4G network s core technology space-time block coded MIMO-OFDM communication system, involving spatial diversity, time diversity and frequency diversity of the organic combination, including QPSK modulation and demodulation, IFFT modulation, control of encoding and decoding, symbol-based channel estimation training and other communication module. Including main_STBC_MIMO_OFDM and training_symbol two M file and a DOC file, have detailed the various parts of the code and comments. )

我设计的遗传算法代码，希望大家能够喜欢，谢谢啊(I design the genetic algorithm code, we want to like, thank ah)
