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.

Abstract: Certain aspects and features are directed to determining characteristics such as phase margin and gain margin of signals such as standardized orthogonal frequency-division multiplexing (“OFDM”) signals. In one aspect, a processing system can identify multiple carriers in an OFDM signal communicated by a repeater. The carriers include carriers from frequency guard band other than those used for communicating payload data or pilot data. The processing system can generate dynamic characteristic data to be sent via the carriers. The processing system can generate modulate the carriers with the dynamic characteristic data. The modulated power level of the carriers is less than a maximum level of noise filtered by a device receiving the OFDM signal.
