本研究考虑了高效多载波通信的调制和解调问题。为了保持紧凑的频谱并实现密集的多载波传输,提出了一种基于随机跳频位置的新型调制方法,即跳时多相移相键控(TH-MPPSK)来消除离散频谱。然后,提供了子载波之间没有保护间隔的多载波方案以降低实际通信系统中的复杂度。此外,提出了一种新颖的解调方法来提高有效的通信性能。仿真结果表明,TH-MPPSK 可以显着去除离散频谱,并且所提出的解调方法具有令人满意的性能。
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.
