Summary:
When a radio signal is transmitted in a real propagation environment with various objects or buildings, the signal may be distorted or impaired because of the diffraction, scattering or absorbing. This situation is specially important on a complex railway environment. Therefore, the channel modeling of propagation on a railway environment becomes a hot research field. As the demands for broadband wireless data transmission raising, it is essential to characterize the wireless channel in modern railway system. In this paper, we designed and manufactured a broadband channel sounder system with high power (42dBm) and covering from 0.5 GHz to 6 GHz in different bands. Otherwise, the receiver provides a sensitivity of -100 dBm with an available gain up to 65 dB. Through the test trials we did in the metro station and tunnels, can prove this channel sounder is able to measure the behave of radio wave propagation that will be very useful for channel modeling in complex environment.
