中文说明： 构成不同频率的调制信号，ldpc码的编解码实现，matlab程序运行时导入数据文件作为输入参数，给出接收信号眼图及系统仿真误码率，搭建OFDM通信系统的框架，用MATLAB实现动态聚类或迭代自组织数据分析。
English Description：
The modulation signals of different frequencies are composed. The encoding and decoding of LDPC code are realized. The data file is imported as the input parameter when matlab program is running. The eye diagram of the received signal and the bit error rate of system simulation are given. The frame of OFDM communication system is built. The dynamic clustering or iterative self-organizing data analysis is realized by MATLAB.
