这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。(This is a space-time block codes based on the MIMO_OFDM Communication System Simulation and Design. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training symbols such as communication channel estimation module.)

least significant bit insertion is done using matlab..data is hidden in the least significant bit of carrier file.

A simple ANN sample code. 2 Layer neuro and the active function is sigmoid.

说明：  有关MATLAB中小波的分析，大家一起分享，希望能对你有帮助(The MATLAB' s edge detection process, to share with everyone, hope you can help)

Example to with crypto providers containers

利用matlab实现数据模糊查询的功能，实现了在不精确数据中验证数据属于那个集合(Matlab fuzzy query data using the function )

用训练序列和lloyd算法，对一个正弦信号数据进行标量量化。(Using the training sequence and lloyd algorithm, we take a sinusoidal signal data for scalar quantization to deepen our understanding.)

说明：  matlab开发函数，一些简单的例子和数字滤波器设计函数(matlab development function, some simple examples and digital filter design function)

QPSK调制解调误码率及误符号率，相干解调，输出的bitber是误码率，symber是误符号率(QPSK demodulator BER and misuse of the symbol rate, coherent demodulation, the output is bitber BER, symber mistakenly Symbol Rate)
