The cumulative distribution function of estimated downlink inter-user channel correlation for all measured channels. This includes estimations by utilizing full downlink channel (labeled as full-channel), approximated downlink channel with downlink dominant angles (labeled as dom-path-channel), downlink dominant angles and amplitudes (labeled as dom-angle-amp), and uplink downlink dominant angles and amplitudes (labeled as UL-dom-angle-amp), respectively
