In this paper, the statistical channel properties and channel modeling of indoor part for high-speed train communication system is presented based on wideband channel measurement at 2.35 GHz. Two configurations of base station (BS) antennas, the omni-directional ceiling antenna and the planar antenna on the wall, are used in the measurement, in order to compare different channel characteristics and...
In order to evaluate the relay performance for IMT-Advanced systems, the propagation characteristics of relay channels are necessary, especially in urban environments. We conducted wideband relay channel measurements at 2.35 GHz in urban environments of China by employing a real-time channel sounder. Three types of links, i.e. base station to mobile station (BS-MS), relay station to mobile station...
Based on the channel measurements at 5.25 GHz in the hotspot area, empirical path loss (PL) models are developed and discussed for the IMT-Advanced system design. The measured scenarios include indoor line-of-sight (LOS), non-LOS, outdoor LOS/obstructed LOS, and outdoor-to-indoor propagations. The PL exponent, intercept, and standard deviation of shadow fading are obtained by using the least square...
