画图时，将图形局部放大，很实用的代码，以前上传过一个m文件，上传错误了，现修正。(When drawing the graphic enlarged, very practical code previously uploaded an m file upload error, now corrected.)

IAR启动分析 在main()之前，IAR都做了啥(IAR start the analysis in main (before), IAR have done what)

STBC_MIMO_OFDM.m 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 ( STBC_MIMO_OFDM.m This is a space-time block coding based on MIMO_OFDM Communication System Simulation. This system consists of QPSK modulation and demodulation, IFFT modulation, space-time coding and decoding, based on training)
