| Abstract(in English) | A proper design and analysis of future wideband wireless communication systems require an accurate radio channel model. This model is claimed to characterize both the spatial and temporal channel characteristics. This paper investigates the spatio-temporal channel modeling based on a ray-tracing approach in the line-of-sight(LOS)pico-cellular environment. This modeling approach is validated by the comparison with experiment results. The temporal channels are characterized by a delay profile. The statistical median delay profile is obtained from ray tracing by incorporating the random phase approach. A high level of agreement between predicted median delay profiles and measured ones is observed in the verification. Next, the spatio-temporal channel impulse response(CIR)predicted from ray tracing is also transformed to have limited band-width and limited beam-width characteristics. The applicability of this transformation is also verified by the comparison with measurement. These verifications prepare the ground for the use of ray-tracing approaches to evaluate system performance in real environments. |
