Abstract: The present invention is a method and system for managing a transmitter located in close proximity to a sensitive receiver. In an exemplary embodiment, the method may include recognizing incomplete receive operations on frequencies that may be affected by co-site transmit operations. Further, the method may include detecting the beginning of a speech message and delaying the speech message up to a selected maximum amount of time. The speech message may be delayed to correspond to required communications performance, allowing receive and transmit operations to be coordinated and thus, reducing the possibility of the receiver to be interrupted or affected by the transmitter operating on a relatively nearby frequency.

Abstract: A quadrature LINC transmission system processes a baseband input signal for transmission as a linearly amplified RF signal. An in-phase LINC element processes an in-phase baseband signal into an in-phase RF signal. A quadrature LINC element processes a quadrature baseband signal into a quadrature RF signal. An output combiner combines the in-phase RF signal with the quadrature RF signal to provide the linearly amplified RF signal. The in-phase LINC element has a constant envelope decomposition block for decomposing the in-phase baseband signal into in-phase baseband constant envelope components. Two up-converters convert the in-phase baseband constant envelope components to in-phase RF constant envelope components. Two non-linear amplifiers amplify the in-phase RF constant envelope components. A combiner combines the amplified in-phase RF constant envelope components to yield the in-phase RF signal. The quadrature LINC element is similar to the in-phase LINC element and provides the quadrature RF signal.

The traffic display provides clear and intuitive means of understanding the flying environment related to the performance of the ITP, increasing situational awareness and simplifying the ITP. The traffic display is specifically advantageous for performance of an ITP, but may be integrated with displays including terrain, weather, flight plan waypoints, or TCAS (Traffic Collision Avoidance System) traffic.
