The 57-64-GHz Unlicensed Band: Correlation Bandwidth Estimation and Comparison for Time-Variant and Static Channels

Results of correlation bandwidth values from narrow-band and wide-band channel sounding measurements made in the same indoor propagation environment of a 63.4-64.4-GHz picocell are presented. The influences of a time-variant and a static channel on the propagation characteristics are investigated. The correlation bandwidth varies significantly with the location of the terminals with lower values less than 5 MHz. It has been observed also for both cases that the correlation values decrease with increasing frequency separation.The spatial characteristics of a millimeter-wave time-variant and static channel are dominant.
