Mengnan Jian, Ruiqi Liu
Abstract
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.
