Abstract: A quadrature detector subjects a received signal to quadrature detection and outputs a base band signal. A direct current component measurement circuit measures a magnitude of a direct current component included in the base band signal from the quadrature detector. A first HPF and a second HPF reduce the direct current component included in the base band signal from the quadrature detector. A demodulator demodulates the base band signal output from the first HPF and the second HPF. A controller exercises control to attenuate a level of the received signal input to the quadrature detector when the magnitude of the direct current component measured by the direct current component measurement circuit is equal to or larger than a threshold value.

Abstract: Antenna monitoring systems and methods can include, among other things, a transmitter near each of the antennas in a distributed antenna system (DAS). The transmitter can transmit an antenna identifier corresponding to that antenna, so that the various transmitters in the DAS each transmit different antenna identifiers. These antenna identifiers can be detected by a receiver and can be processed to determine whether any antenna identifiers are missing. If any expected antenna identifier is missing, the receiver can infer that the antenna or a component associated with the antenna (such as cabling) may have failed. The receiver can then output an indication or notification that may be accessed by maintenance personnel and/or emergency personnel to enable them to identify and repair the non-functioning antenna or component. The transmitter can transmit other data, such as environmental data, RF data, or the like, to facilitate additional or alternative monitoring functionality.
