Patent ID: 8571470

Claim:
A system for repeating signals, the system comprising: at least one receive antenna for receiving input signals, processing circuitry for processing the input signals to form repeated signals and at least one transmit antenna for transmitting the repeated signals; the processing circuitry including: circuitry configured to generate cancellation signals that are added to the input signals to attenuate feedback signals in the input signals; circuitry for modifying the repeated signals prior to their transmission so that the repeated signals are transmitted, as modified, by the at least one transmit antenna, the repeated signals being modified with respect to the received input signals to differentiate the modified repeated signals, that are received as feedback through the at least one receive antenna, from the input signals; processor circuitry coupled to the circuitry configured to generate cancellation signals, the processor circuitry operable for affecting the way the cancellation signals are generated, the processor circuitry configured for utilizing the modified repeated signals for affecting the way the cancellation signals are generated.
