摘要： A signal repeating system includes at least one input antenna that receives input signals, at least one output antenna that radiates output signals, and a signal path between the input and output antennas. The signal path includes circuitry for conditioning the input signals with down conversion circuitry that converts input signals to lower frequency signals and analog-to-digital conversion circuitry that converts the input signals to digital signals. A suppression circuit suppresses feedback and interference in the repeated output signals with a digital signal processor configured for receiving samples of the input signals, samples of the output signals, and samples of an interference reference signal and an adaptive filter under the control of the digital signal processor for generating echo cancellation signals and interference cancellation signals.

摘要： A switching control module can optimize time division duplexing operations of a distributed antenna system (“DAS”). The switching control module can include a measurement receiver and a processor. The measurement receiver can measure signal powers of downlink signals in a downlink path of the DAS. The processor can determine start times for downlink sub-frames transmitted via the downlink path based on downlink signal powers measured by the measurement receiver exceeding a threshold signal power. The processor can identify a clock setting that controls a timing of switching signals used for switching the DAS between an uplink mode and a downlink mode. The processor can statistically determine a switching time adjustment for the clock setting based on switching time differentials between the clock setting and the start times. The processor can update the clock setting based on the switching time adjustment.

摘要： The present disclosure describes devices, systems, and methods for synchronizing multiple-input/multiple-output (“MIMO”) signals or other signals in telecommunication systems. Some aspects may involve transmitting signals between a head-end unit and remote units of a telecommunication system. A first delay of a signal path between the head-end unit and a first remote unit of the remote units may be determined to be greater than each delay of signal paths between the head-end unit and other remote units. Based on the first delay, the telecommunication system may be configured to delay transmission of additional signals such that the additional signals are simultaneously transmitted to another unit by either the head-end unit or the remote units.

摘要： A mobile testing system for optimizing wireless coverage in a distributed antenna system is disclosed. In some aspects, the mobile testing system includes a measurement receiver that can determine signal levels for a respective signals communicated via the distributed antenna system. A processing device of the mobile testing system can identify a subset of the signals by decoding a respective identifier encoded in each of the subset of signals. The identifiers specify that the subset of signals is targeted to at least one coverage zone in which the mobile testing system is located. A subset of signal levels is obtained by the measurement receiver that corresponds to each of the subset of signals. The processing device can generate coverage contour data based on the subset of signal levels that describes signal coverage for at least one coverage zone.
