Measuring the Impact of Beamwidth and Bandwidth on the Wide-Sense Stationarity of Millimeter-Wave Channels

IEEE Open Journal of the Communications Society, 2023
If a wireless channel is said wide-sense stationary (WSS), the mean and autocorrelation of its small-scale fading are position invariant. This occurs when the channel is rich in propagation paths – their complex summation averages out any position-
