摘要： 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.

摘要： A system and method of monitoring a signal repeating device in a wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first element, but within a bandwidth of a second, subsequent element in a signal path of the device. The operational noise measurement is alternatively obtained by tuning an input band of the device to shift the input band partially or completely outside of a bandwidth of a first element to create an open band or by suppressing an input of an antenna and measuring noise within the open bandwidth of the device. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the device may be received at a signal receiver and compared to a reference. The reference is a function of elements of the device in a leakage path of the leakage signal.

摘要： Embodiments of the invention provide a method, distributed antenna system, and components that generate a jitter reduced clock signal from a binary encoded data stream transmitted over a communication medium. The method includes receiving a modulated signal that includes the binary encoded data stream and generating a recovered clock signal that is phase locked to the binary encoded data stream. The method further comprises generating a stable recovered clock signal by filtering the recovered clock signal to remove jitter, while allowing the clock signal to track long-term drift.

摘要： A method and apparatus for controlling uplink signal power in a distributed antenna system 10 having a master unit 22 and a plurality of remote units 14 and coupled with a base station 12 includes monitoring a noise condition of the distributed antenna system. The invention dynamically adjusts an uplink gain within the distributed antenna system 10 that is applied to uplink signals to a base station 12, based on the monitored noise condition. Monitoring the noise condition in the distributed antenna system 10 includes monitoring one or more remote units 14 of the plurality of remote units and determining if the remote unit is active status or mute status and then. The uplink gain is increased in response to a decrease in the number of remote units that are active status and decreased in response to an increase in the number of remote units that are active status.

摘要： A distributed antenna system having improved data transmission features incorporates endpoints of the system, which are coupled together by serial data link. At the endpoints, processing may occur utilizing processing circuitry to determine similarities between multiple signal streams. If the streams are similar, the data sent over the serial digital link is reduced by only sending one of the representative signals. In an alternative embodiment of the invention, the difference between the signals might be sent as well. Alternatively, all signals might be sent, but may be compressed with compression circuitry before the signals are transmitted over the serial link. At the endpoint of the system, the signals are reconstructed for further processing and transmission.
