    Abstract: One embodiment is directed to a distributed antenna system in which a setting for automatic gain control functionality in at least one unit included in the system (for example, in a hub unit or a remote unit) is determined by interpolating between two detected levels measured at that unit while the automatic gain control functionality is operating in two respective predetermined configurations and by interpolating between two target levels that are associated with the two respective predetermined configurations. In one example, the intersection of the two resulting interpolations is used to determine the setting for the automatic gain control functionality.

    Abstract: A communication system comprises a first unit; and a second unit communicatively coupled to the first unit. The first unit is operable to receive a first original radio frequency signal via a first interface and the second unit is operable to receive a second original radio frequency signal via a second interface. The second unit is operable to output a first reproduced radio frequency signal via the second interface, the first reproduced radio frequency signal being derived from the first original radio frequency signal. The first unit is operable to output a second reproduced radio frequency signal via one of the first interface and a third interface, the second reproduced radio frequency signal being derived from the second original radio frequency signal. The first interface is operable as a simplex interface when the second reproduced radio frequency signal is output via the third interface and as a duplex interface when the second reproduced radio frequency signal is output via the first interface.

    Abstract: A method of determining a boundary of a subframe in a time division duplexing (TDD) system is provided. The method detects a power level of a signal on at least one radio frequency, the signal comprising at least one subframe. A time-domain correlation is done on the detected signal with a first reference signal, wherein the first reference signal represents at least one subframe. The location in time of a boundary of the at least one subframe of the detected signal is determined based on the correlation of the detected signal and the first reference signal.

    Abstract: A method for determining an end of a first period in which signals are communicated in a first direction is provided. The method comprises sampling a signal for a period of time up to at least as long as the longest expected length of the first period to obtain a sampled signal. The sampled signal is integrated to obtain an integrated power curve. A reference line is subtracted from the integrated power curve to obtain a rotated power curve. A peak in the rotated power curve is selected as an end of the first period.
