Abstract
As one of the core technologies of 6G and future wireless communication, terahertz communication has significant advantages of super bandwidth and high transmission rate, but its development still faces many key technical bottlenecks. This paper aims to explore the challenges of terahertz communication in hardware implementation, channel modeling, modulation and demodulation, and energy consumption optimization, and propose possible theoretical breakthroughs. Device designs based on new semiconductor materials can effectively improve system efficiency, while intelligent beamforming and multi-user access strategies significantly improve spectrum utilization and energy consumption. The main contribution of this paper is to propose a dynamic resource allocation fr amework suitable for terahertz frequency bands and verify its feasibility in practical scenarios. In addition, the research also emphasizes the importance of interdisciplinary cooperation, which provides theoretical basis and practical guidance for the development of terahertz communication technology in the future.
