300HZ 采样率下，50、60HZ陷波器及8HZ高通多项式实现。画出原始数据及滤波后数据并画出相应频谱(50/60HZ notch filter of the matlab program.Plot raw data and filtered data and corresponding Spectrum)

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 applications of IM: spatial modulation (SM) and orthogonal frequency division multiplexing with IM (OFDM-IM), and we discuss the recent advances and future research directions in IM technologies towards spectral and energy-efficient 5G wireless networks.
