Abstract: Various communication systems may benefit from suitable architectures. For example, L-band radio frequency (RF) architectures may be beneficial to systems including avionics systems. A system can include a mode-s function as well as a traffic alert and collision avoidance system function separate from the mode-s function. The system can further include a directional antenna in reception and transmission connection with the traffic alert and collision avoidance system function. The system can additionally include an omni-directional antenna in reception and transmission connection with the mode-s function.

Abstract: Various communication systems may benefit from enhanced reception methods. For example, various transponders and surveillance systems may benefit from reception methods that can distinguish between overlapping pulses from multiple sources. A method can include receiving, at an antenna, a first series of pulses from a first source. The method can also include receiving, at the antenna, a second series of pulses from a second source. The first series and the second series can at least partially overlap each other. The method can further include de-interleaving the first series from the second series using at least one non-time-domain technique.

Abstract: Various systems may benefit from the appropriate interworking of subsystems. For example, various avionics systems and method may benefit from the integration of terrain and/or weather avoidance, for example with other detection and avoidance subsystems. A method can include determining, by an avionics system, a hazard condition with respect to an ownship aircraft. The method can also include generating, by the avionics system, a maneuver inhibition based on the determined hazard condition. The method can further include providing the maneuver inhibition to a traffic avoidance or alerting system.
