Abstract

Aspects and features are directed to an uplink integrity detection sub-system. In one aspect, a distributed antenna system is provided that includes at least one master unit; a plurality of remote antenna units each in communication with the at least one master unit; and a system controller configured to: determine a noise figure for an uplink path from at least one of the plurality of remote antenna units; and modify a gain of the uplink path when the noise figure exceeds a desired threshold, wherein the noise figure is determined as a function of a measured signal power of an undesirable signal component in the uplink path from the remote antenna unit.
