Orthogonal Frequency Division Multiplexing with Index Modulation,is proposed for operation over frequency-selective and rapidly time-varying fading channels

we shed light on the potential and implementation of index modulation (IM) techniques for MIMO and multi-carrier communications systems which are expected to be two of the key technologies for 5G systems. Specifically, we focus on two promising appli

本代码是关于正交频分复用索引调制的仿真代码(Orthogonal frequency division multiplexing index modulation simulation code)

本仿真系统主要针对光OFDM系统，但需要注意的是，本系统还不能够直接用于采用强度调制直接检测（IM/DD）的光通信系统。因为采用IM/DD的光通信系统，其发送端是把要传送的信息转变为电流信号注入LD或LED，从而获得相应的光信号，这就要求要传送的信号必须为正且实的信号，然而经本系统中IFFT得到的时域信号虽然全为实的，但含有负数，这对于采用IM/DD的光通信系统是不行的。

ofdmIM仿真系统设计源代码，有不对的地方请指教谢谢大家(Ofdmim simulation system design source code, there are wrong places please advise, thank you)
