| 20110263195 | USE OF STEERING SIGNALS IN INTERFERENCE CANCELLATION WITH APPLICATION TO COMMUNICATION THROUGH SIGNAL JAMMING - A system and method are provided for transmitting a broadband interference signal and allowing communication through the transmitted interference signal. The system includes an interference transmitter for transmitting the interference signal, the interference transmitter having a transmitter feeder and a first antenna; a radio receiver for receiving a radio signal, the radio receiver having a radio feeder and a second antenna collocated with the first antenna of the interference transmitter; a steering signal generator for introducing at least one steering signal into the interference signal at the transmit feeder; a first directional coupler for sampling a portion of the interference signal that includes at least one of the steering signals; a negative feedback loop for adjusting the amplitude and phase of the sampled portion of the interference signal; and a second directional coupler for coupling the adjusted sampled portion of the interference signal into the radio feeder. | 10-27-2011 |
