Validation of Deterministic Radio Channel Model by 10 GHz Microcell Measurements

摘要

This paper considers validation of a deterministic radio channel model utilizing wideband radio channel measurements at 10 GHz frequency. Multiple-input multiple-output radio channel measurements were carried out in urban microcell type of environment. The validation comprises of analysis and comparison of modeled propagation paths and measured propagation paths. From the measured data, the azimuth and elevation (3D) angles, gains and delays of propagation paths were estimated. With the deterministic model the propagation paths were modeled by a map-based model utilizing simplified ray-tracing with buildings modeled as rectangular shapes. The 3D map for the deterministic model was created based on the collected distance information of the measurement site. Both line-of-sight (LOS) and non-line-of-sight (NLOS) propagation conditions were considered. Path losses, power delay profiles, and the directions of departure and arrival were used to validate the model. The path losses are similar, and the directions of the modeled and measured paths match well.
