Abstract

Abstract

With the foundation of multi-carrier modulation based on Prolate Spheroidal Wave Functions (PSWFs) with signal grouping optimization, the idea of dual-mode index modulation is introduced, and proposes a method of Multi-Carrier index Modulation based on PSWFs with Dual-Mode (DM-MCM-PSWFs) is introduced. The remaining sub-carriers that are not activated to load the modulation symbols generated by the second constellation to transmit additional information bits are used in this method, resulting in the improvements of efficiency of spectrum resources in multi-carrier modulation based on PSWFs with signal grouping optimization, and it improves effectively the system spectral efficiency and error performance. Theoretical and simulation analysis indicate that compared with multi-carrier modulation based on PSWFs with signal grouping optimization, the proposed method can attain higher system spectral efficiency and better system error performance at the expense of acceptable sacrifice of system complexity. When the bit rate is 1×10^-5, n=7, and k=3, the system spectral efficiency and error performance of the proposed method can increase by 9.15% and 2.4 dB respectively.
