Abstract: A feed-forward cancellation system includes a transmitting element and a receiving element. The transmitting element is in electrical communication with a transmitting line. The transmitting element is configured output a transmission signal to the transmitting line. The receiving element is in electrical communication with a receiving line. The receiving element is configured to process a response signal that is generated in response to the transmission signal and that is delivered to the receiving line. At least one antenna is configured to transmit the transmission signal, receive the response signal generated based on the transmission signal, and deliver the response signal to the receiving line. The feed-forward cancellation system further includes an electronic cancellation unit configured to generate a cancellation signal based on the transmission signal. The cancellation signal eliminates saturation from at least one of the response signal and the receiving line.

Abstract: A wideband radio frequency (RF) interference cancellation system includes an electronic channel canceller configured to split an electronic reference signal output from an electronic transmitting element into a plurality of band signals. At least one electronic band pass filter is configured to receive a respective band signal delivered to a respective channel. The wideband RF interference cancellation system further includes at least one electronic tunable cancellation element configured to tune the respective channel such that reflections are canceled before being input to receiving element.

Abstract: Disclosed subject matter relates to techniques for predicting jamming effectiveness. In one approach, platform models and propagation models are used to predict maximum threat communication range when jamming is used and when jamming is not used. The maximum range information may then be used to calculate jammer effectiveness. In another approach, probability-based techniques are used to predict jamming effectiveness for a system of interest.

Abstract: A rake receiver and method for operating a rake receiver is provided including receiving a signal in a rake receiver having at least one finger, each of the at least one finger characterized by a channel phase and a channel frequency, removing a phase and a portion of the frequency component of the signal in a first block of the at least one finger, and removing a remaining frequency component of the signal in a second block of the at least one finger.
