1. A method comprising:

  • receiving, via an uplink path of a wideband remote unit of a distributed antenna system, wideband signals comprising an uplink RF signal and a leaked downlink RF signal, the uplink RF signal having an uplink signal power and the leaked downlink RF signal having a downlink signal power greater than the uplink signal power, wherein the leaked downlink RF signal is from a downlink RF signal transmitted by the wideband remote unit;

    converting, by the wideband remote unit, the received wideband signals to a first digital RF signal that represents the uplink RF signal and to a second digital RF signal that includes the leaked downlink RF signal; and

    transmitting, in the uplink path from the wideband remote unit, the first digital RF signal and the second digital RF signal to a unit of the distributed antenna system in communication with a base station;

    wherein the uplink path of the wideband remote unit is configured with a dynamic range having a minimum value and a maximum value suitable to digitize both the uplink RF signal and the leaked downlink RF signal.
