Multi-carrier Index Modulation Method Based on PSWF-CPM Signal

Abstract— Index modulation is a hot spot in the research of multi-carrier modulation technology in wireless communication, on the basis of the traditional multi-carrier index modulation method in frequency domain, in this paper, the signal of prolate spheroidal wave functions (PSWF) with the best energy concentration in time-frequency domain is taken as the multi-carrier transmission waveform, continuous phase modulation (CPM) symbol mapping mode is adopted, a multi-carrier index modulation method based on PSWF-CPM signal is proposed. At the receiving end, the method of greedy detection (GD) and CPM difference decomposition mapping is used to realize the detection and demodulation of low complexity signals. The method can effectively reduce the peak-to-average power ratio (PAPR) of PSWF-CPM modulation signal according to the change of CPM modulation index, and the GD detection method is insensitive to imperfect channel state information (CSI), and the implementation complexity is relatively low.
