摘要： A system to monitor gain in a broadband radio frequency transport system that includes a radio frequency antenna, a remote unit, and a host unit adapted to receive a signal from the remote unit over a transmission link. The remote unit includes a pilot tone generator adapted to generate at least one single-frequency tone having a known power level, a summing circuit operably associated with the pilot tone generator adapted to sum the single-frequency tone with the respective received radio frequency signal. Each host unit includes a pilot tone receiver circuit to receive the transmitted signal and detect the single-frequency tone transmitted over the transmission link. The host unit includes a controller to determine a gain within the transmission link and to determine if the gain is in a preset range of gains based on the power level of the received pilot tone.

摘要： A communication system to feed remote antenna nodes with simulcast traffic and non-simulcast beacons is provided. The communication system includes a host radio frequency (RF) digitizer, a delay buffer, a summing circuit, and a framer/serializer. The host RF digitizer receives CDMA base station signals for simulcast CDMA-traffic-bearing channels and to output digital samples. The delay buffer is communicatively coupled to receive the samples output from a beacon pilot generator and to output digitally delayed CDMA-digital-beacon-pilot samples having different pseudo-noise offsets. The summing circuit adds the CDMA-digital-beacon-pilot samples having different pseudo-noise offsets to the digital samples received from the host RF digitizer to form composite simulcast-plus-uniquely-offset-beacon-pilot CDMA samples. The framer/serializer is communicatively coupled to receive the composite simulcast-plus-uniquely-offset-beacon-pilot CDMA samples, and to route the composite simulcast-plus-uniquely-offset-beacon-pilot CDMA samples to an associated remote antenna node.

摘要： A method and system for enhancing the performance of wideband digital RF transport systems, which enables the selection of a serial data rate to be transported over a transport medium. Thus, the present invention allows the system to be adapted to different transport mediums, and allows the user to set the serial data rate based on the input bandwidth of the system. The present invention also enables the transport of different bandwidth segments on a plurality of wideband channels by selecting an optimal clock sample rate for each bandwidth segment to be transported. Thus, the present invention allocates the bandwidth segments proportionally so that an optimum amount of bandwidth can be transported at the serial bit rate.
