| Abstract(in English) | Millimeter wave (mmWave) band has been deployed in the 5th generation mobile communication system to realize the enhanced mobile broadband service (eMBB). Though severe propagation loss at mmWave is compensated by pointing the main beam of the base station antenna to the line of sight (LoS) toward the mobile stations, there is a deep shadow fading, when a moving object such as a human body, blocks the LoS. To evaluate and predict the impact brought by the dynamic blocking object, simultaneous dynamic channel sounding and posture capturing using RGB-D video camera, in which the measurement time stamps must be synchronized, is needed. This study proposes the synchronization algorithm between two different instruments by using a visible laser. The blocking sensor of the laser beam triggers the spectrum analyzer. This trigger timing is synchronized with the first video frame of the appearance of the laser spot on the surface of the blocking object. |
