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 multichannel 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.
