METHOD OF INSERTING CDMA BEACON PILOTS IN OUTPUT OF DISTRIBUTED REMOTE ANTENNA NODES |
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. |
