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. )

说明：  信道编码的matlab程序，CRC校验码，RS码，卷积码，turbo码，TCM码(Matlab program channel coding, CRC check code, RS code, convolutional codes, turbo codes, TCM code)

此函数用于求得多重小波变换后的低频小波系数，在matlab自带的函数基础上改的。(this function to obtain multiple wavelet transform the low-frequency wavelet coefficients, In Matlab built-in function on the basis of reform.)

说明：  sdif算法，matlab代码，注释乱码，介意慎点(SDIFsoftware matlab please download)

用matlab写的模糊RBF辨识程序，做成了一个函数。(it is very important.)

通过此函数能实现两个序列的互相关运算，应用比较广泛(Used widely by the cross-correlation operation of this function to achieve the two sequences)
