Abstract: In an embodiment, a method comprises: sending a message from a master unit of a distributed antenna system to a remote unit of the distributed antenna system, wherein the message includes a list of service frequencies and applied standards for a base station; sending a downlink signal generated based on a base station signal from the master unit to the remote unit; decoding the downlink signal based on the list of service frequencies and applied standards for the base station; extracting a base station clock signal from the decoded downlink signal; and synchronizing an internal clock of the remote unit to the base station clock using the extracted base station clock signal.

Abstract: A communication system and method for extending coverage of a base transceiver station. The communication system includes processing circuitry that receives a communication signal over a wireless channel. The received communication signal is processed through an adaptable equalizer to reduce noise, distortion, interference, and frequency errors. In another aspect of the invention, a frequency of a reference signal in the communication system is adjusted to compensate for frequency errors between the communication system and the source of the communication signal. The equalized and frequency adjusted communication signal is then retransmitted into an extended coverage area. Wireless coverage is thereby provided between a base transceiver station and a mobile device in the extended coverage area.
