通过MATLAB对4G OFDM基带系统进行仿真模拟，对系统性能进行分析，以待后进学习研究。-By MATLAB on 4G OFDM baseband system simulation, system performance analysis to be less advanced study and research.

OFDM PAPR Reduction for B3G or 4G mobile wireless communication system.

降低OFDM性能通过设置门限值，这是个完整的程序拿来就能用的。详细列出了papr的详细算法-inorder to reduce the OFDM papr system perfermance, this code implemented by clipping code. this is efficiency and useful. basic on the matlab langurage.

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 t

MIMO-OFDM is a high data rate system in the 4G.
