Abstract
Ray-tracing method was used to simulate the characteristic of wide band radio wave transmission in tunnel. The simulation results showed that the root-mean-square delay spread /spl tau//sub rms/ caused by multipath propagation fade varied with the communication distance in tunnel. Therefore the correlation bandwidth of the channel was connected with the communication distance in tunnel. The attenuation caused by multipath propagation fade varied with the communication distance too.
