太赫兹对于提高数据速率、支持超密集连接、实现低时延传输有着显着的效果。本文研究了太赫兹频谱的特殊性，研究了太赫兹技术的传播特性，并讨论了其信道建模特征。针对太赫兹频段独特的频谱特性，相应地设计了物理层波形、调制、编码方案，以降低峰均功率比（PAPR），增加频谱灵活性，满足后向兼容性，提高系统性能。本文对太赫兹信号的基带信号处理进行了分析和讨论，对未来太赫兹通信系统的设计具有启发意义。
Terahertz has an emphatic effect on increasing data rates, supporting ultra-dense connections, and realizing low-latency transmission. In this paper, we investigate the peculiarity of the terahertz spectrum, study the propagation characteristics of terahertz technology, and discuss its channel modeling feature. Given the unique spectral characteristics of terahertz bands, physical layer waveforms, modulation, coding schemes are designed accordingly to reduce the peak-to-average power ratio (PAPR), increase the spectral flexibility, meet the backward compatibility and improve the system performance. The baseband signal processing of terahertz signals is analyzed and discussed in this paper, inspiring the design of future terahertz communication systems.
