Abstract: Method and apparatus for generating a jitter reduced clock signal from signal transmitted over a communication medium includes receiving, with high speed data interface circuitry, a modulated signal that includes a binary encoded data stream. A recovered clock signal is generated from the modulated signal and tracks the long-term drift in the modulated signal. A jitter reduced clock signal is generated by filtering the recovered clock signal with a filtering circuit having a bandwidth sufficient to remove jitter while allowing the jitter reduced clock signal to track the drift in the modulated signal.

Abstract: Certain features relate to configuring a distributed antenna system (“DAS”) to interface with and manage components of facility control and monitoring systems while providing wireless communications in a cellular or public safety network. A communications module is configured for receiving facility control signals from facility control and monitoring centers and associated nodes and sensors. A signal processing module is configured to convert the facility control signals a format transportable in the DAS. The signal processing module is also configured to multiplex the facility control signals with mobile voice and data signals being transported in the DAS. The DAS configured to manage components of facility control and monitoring systems can route facility control signals to appropriate facility control centers or the nodes and sensors associated with the facility control centers.

Abstract: Certain aspects involve a wideband remote unit. The wideband remote unit can include one or more antennas and an analog-to-digital converter (“ADC”). The antenna can receive wideband signals. The wideband signals can include an uplink RF signal and a leaked downlink RF signal. The uplink RF signal can have an uplink signal power at or near a noise level. The leaked downlink RF signal can have a downlink signal power greater than the uplink signal power. The ADC can convert the received wideband signals to digital RF signals representing the uplink signal and the downlink signal. The wideband remote unit can transmit the digital RF signals to a unit of a DAS that is in communication with a base station.

Abstract: An endpoint element of a distributed antenna system includes processing circuitry configured for processing a plurality of digital signals for conditioning the signals and compression circuitry configured for compressing at least one of the digital signals according to a compression scheme to yield at least one compressed digital signal and compression settings. The digital signals are combined into a single digital stream and combined and time division multiplexed onto a serial data link with the compression settings. The digital signals are also transmitted with compression settings to another endpoint element over the serial data link.

Abstract: A method of controlling uplink signal power in a distributed antenna system includes monitoring a noise condition of an uplink signal path in the distributed antenna system and determining the noise contribution from the distributed antenna system that is presented to the base station. The receive noise floor of the base station is determined. The determined noise contribution and receive noise floor are unlisted. Based on the evaluation, the uplink gain that is applied to uplink signals from the distributed antenna system to a base station is adjusted.

Abstract: A master unit for use within a distributed antenna system includes: re-sampling devices configured to output re-sampled digital downlink signals by re-sampling digital downlink signals at customized resample rates based on at least one factor, the re-sampled digital downlink signals having a smaller bandwidth than the digital downlink signals; and a framer configured to multiplex the re-sampled digital downlink signals and to generate a first frame that includes the re-sampled digital downlink signals as framed data for transport to one or more remote units of the distributed antenna system, wherein the one or more remote units of the distributed antenna system are configured to transmit radio frequency signals using at least one antenna, wherein the transmitted radio frequency signals are derived from the framed data of the first frame received from the master unit.

Abstract: Embodiments are disclosed for extracting sub-bands of interest from signals in a frequency domain for transmission via a distributed antenna system. In one aspect, a transformed downlink signal is generated by performing a frequency transform on a downlink signal. The transformed downlink signal represents the downlink signal in a frequency domain. At least one sub-band of the transformed downlink signal is identified as including data to be transmitted via the distributed antenna system. The sub-band is extracted from the transformed downlink signal for transmission via the distributed antenna system.
