| 英文摘要: |
| Based on the analysis of the impact of Doppler shift to the railway dedicated mobile communication quality under the condition of high-speed mobility, this paper presents a Doppler shift measurement approach based on the phase estimation of frequency correction channel (FCCH) which correctly reflects the time-varying characteristic of the channel with a testing system developed. The Doppler shift data under the high-speed condition is collected, processed, analyzed, and compared with the simulation results. The scientific laws of the Doppler shift distribution of radio channel under high-speed condition are obtained. These data and analysis are essential for the establishment of high-speed railway Doppler power spectrum model and the development of the key technology of anti-Doppler shift. |
