Spatial and temporal characteristics of 60-GHz indoor channels

摘要

This article presents measurement results and models for 60-GHznchannels. Multipath components were resolved in time by using a slidingncorrelator with 10-ns resolution and in space by sweeping a directionalnantenna with 7° half power beamwidth in the azimuthal direction.nPower delay profiles (PDPs) and power angle profiles (PAPs) werenmeasured in various indoor and short-range outdoor environments.nDetailed multipath structure was retrieved from PDPs and PAPs and wasnrelated to site-specific environments. Results show an excellentncorrelation between the propagation environments and the multipathnchannel structures. The measurement results confirm that the majority ofnthe multipath components can be determined from image based ray tracingntechniques for line-of-sight (LOS) applications. For non-LOS (NLOS)npropagation through walls, the metallic structure of composite wallsnmust be considered. From the recorded PDPs and PAPs, received signalnpower and statistical parameters of angle-of-arrival and time-of-arrivalnwere also calculated. These parameters accurately describe the spatialnand temporal properties of millimeter-wave channels and can be used asnempirical values for broadband wireless system design for 60-GHznshort-range channels
