With the rapid advancement of the Internet of Things, terahertz band has emerged as a prominent area of research for high-speed wireless communication over the past decade to satisfy the growing demand for network traffic and is extensively employed in indoor wireless communication systems. This study experimentally examines the transmission efficacy of MSK signals in terahertz channels via upconversion. In the LabVIEW development environment, the PN sequence serves as the baseband signal. The MSK signal, with a bandwidth of 1GHz and a transmission rate of 1Gbit/s, is modulated and output using the high-speed vector signal transceiver platform, PXIe-5841. This signal is then upconverted to 230~300GHz for wireless transmission. The findings from the constellation and grid diagrams reveal the stable and reliable transmission of the MSK signal in the terahertz communication system, underscoring its viability and potential for future research and application.
