摘要：
This study investigates the performance of a multi-channel access solution based on a robust terahertz indoor communication system at 325 GHz with a single-input, single-output (SISO) system. Spatial diversity builds up the possibility of transmission under various channel conditions. The wireless terahertz system comprises a vibration mirror, a blocking object, two motorized stages, and two lenses. The system imitates the actual communication scenarios affected by blockage and misalignment. We adopted three multi-channel strategies: (1) Line-of-sight transmission (2) Reflection transmission (3) Blockage along LOS transmission. With experimental results, we validate our analysis and successfully show that the multi-channel strategies can significantly improve transmission. The SISO system can have a coverage of 115 degrees with a wireless distance of 1.5 meters. The results greatly impact the applications of terahertz indoor communications and provide a physical solution for various transmission conditions.
