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

MIMOOFDM_Syn为主函数，仿真了传统的sc同步算法，并在此基础上做改进。对定时误差和频偏误差做了计算并画图。%信号通过的多径衰落信道为7径瑞利衰落信道且各径功率随着延迟的增大服从负指数衰减。
