研究目的
Investigating the development of a 3-D statistical channel impulse response model for urban LOS and NLOS channels at 28 and 73 GHz to support the design of 5G wireless systems.
研究成果
The paper presents a 3-D statistical channel model for mmWave LOS and NLOS communications, validated through extensive measurements. The model supports the design of 5G wireless systems by accurately reproducing realistic channel impulse responses and power angular spectra.
研究不足
The model is valid for RF bandwidths up to 800 MHz and antenna beamwidths greater than 7°. The study focuses on urban environments in New York City, which may not represent all urban settings.
1：Experimental Design and Method Selection:
Utilized a 400-megachips-per-second broadband sliding correlator channel sounder for 28- and 73-GHz wideband urban channel measurements. Directional steerable horn antennas were used for TX and RX azimuth sweeps.
2：Sample Selection and Data Sources:
Measurements were conducted in New York City with T-R separation distances ranging from 20 to 425 m.
3：List of Experimental Equipment and Materials:
Included a broadband sliding correlator channel sounder, steerable directional horn antennas, and LabVIEW post-processing software.
4：Experimental Procedures and Operational Workflow:
PDPs were recorded at various azimuth and elevation angles, with absolute propagation times recovered using 3-D ray-tracing software.
5：Data Analysis Methods:
Statistical distributions were extracted from measured data to model temporal and spatial channel parameters.
