Experimental Assessment of a Method to Perform High Velocity Measurement at Low Velocity

High-Speed Railway (HSR) measurement is very difficult, with the limitation of policy, complexity, cost and safety constraints. A technique performing high velocity measurement at low velocity has been proposed in the existing literature, which has not been studied well in the measurement environment. In this paper, the experimental assessment of this technique from the perspective of wireless channel parameters is presented. Specifically, two controlled measurements at the center frequency of 465 MHz are conducted, then the channel characteristics such as path loss, shadowing fading, Doppler frequency shift and K-factor are compared. The results verify the feasibility of this technique, and further more can be helpful for channel modeling and network optimization of HSR wireless communication.
