Efficient modulation and demodulation methods for multi-carrier communication

Abstract(summary):

The modulation and demodulation problems for efficient multi-carrier communications are considered in this study. To maintain compact spectrum and realise dense multi-carrier transmission, a novel modulation method based on random hopping position, namely time hopping m-ary phase position shift keying (TH-MPPSK), is proposed to remove the discrete spectrum. Then, a multi-carrier scheme without guard interval among subcarriers is provided to reduce complexity in the practical communication systems. Moreover, a novel demodulation method is proposed to improve the efficient communication performance. Simulation results demonstrate that the TH-MPPSK can significantly remove the discrete spectrum and the proposed demodulation method can satisfactory performance.
