| Abstract: | According to the quasi-high-speed railway transmission requirements of the radio cab signal and the wave propagation characteristics,the Rayleigh propagation model in 460 MHz is modified and validated by the measurement results of a quasi-high-speed railway.The simulation and analysis of the high-speed channel propagation characteristics is then done with the help of the modified Rayleigh fading model. |
