研究目的
To present a 3-D statistical channel impulse response (IR) model for urban line of sight (LOS) and non-LOS channels developed from 28- and 73-GHz ultrawideband propagation measurements in New York City, useful in 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 for link, local area, and track CIRs, with arbitrary carrier frequency, signal bandwidth, and antenna beamwidth, invaluable in the design of next-generation 5G mmWave cellular networks. The simplicity of the presented statistical IR model stems from the independent modeling of time and space, allowing for simple statistical distributions to promote ease of use in simulated software and hardware implementations, while reproducing physically based CIRs and 3-D power angular spectra based on real-world measurements.
研究不足
The model is valid for a 2.5-ns multipath time resolution (800 MHz) and antenna beamwidths of 7°–10°. However, it is also possible to synthesize omnidirectional and directional CIRs for bandwidths less than 800 MHz and for angular resolutions greater than 7°.
