摘要
To cope with the emergence of future high-throughput communication systems such as mMTC, URLLC, or indoor IoT communication, the development of communication spectrum towards higher frequencies is inevitable. In today's spectrum, the terahertz band is a promising range, spanning from 100 GHz to 10 THz, capable of carrying nearly hundreds of times more data throughput than 5G communication systems.This article applies the Non-Orthogonal Multiple Access (NOMA) technique to indoor THz system transmission, marking the first verification of its feasibility in real THz system transmission. Power-domain NOMA allows for the transmission of data to both near-field and far-field users with limited power, utilizing the same spectrum resources for both users. This approach brings higher spectrum efficiency to the next generation of communication systems.
