Abstract
This paper presented a novel millimeter-wave channel measurement platform for the 6G intelligent railway. This platform used phased array antenna with 64 elements and can support instant bandwidth up to 1 GHz. Combined with improved multi-tone sounding signals, the platform can enhance dynamic measurement capability in high-speed railway scenarios. We performed calibration works about frequency flatness, frequency offset and proved platform reliability with channel emulator based closed-loop verification. We also carried out field trials in high-speed railway carriage scenarios. Based on measurement results, we extracted channel characteristic parameters of path loss, power delay profile and delay spread to further verify the field measurement performance of the platform.
