    摘要: The present disclosure relates to the area of telecommunication, and in particular to methods for reporting network dysfunction in a wireless communication network (1). According to a first aspect of embodiments herein it is provided a method, for use in a wireless communication device (10), for reporting network dysfunction. The method comprises obtaining information defining radio communication properties (e.g. use of a relaying wireless communication device (30)) for use when reporting network dysfunction in a wireless communication network (1). The method further comprises detecting network dysfunction, and sending a report indicating the detected network dysfunction e.g. to a radio network node 20 using the obtained radio communication properties. The disclosure also relates to a corresponding radio network node (20) and wireless communication devices (10), (30) and to a computer program for implementing the proposed method.

    摘要: A communications system and methods for covert communications are provided. A first transmitter that transmits an information carrying signal to a target receiver, a second transmitter and a third transmitter transmit jamming signals to the target receiver, such that the information carrying signals and the jamming signals are interleaved when received by the target receiver The information carrying signals and the jamming signals can be at least partially overlapping by an eavesdropper.

    摘要: Disclosed is a system and method for detecting false Global Navigation Satellite System (GNSS) satellite signals. False GNSS satellite signals can be used malevolently to take control of a body such as a vehicle or ship that is using GNSS satellite signals for navigation. In some embodiments a GNSS attitude system is used to detect the false GNSS satellite signals. The GNSS attitude system measures the code or carrier phase of the GNSS satellite signals at two or more antennas to detect the false GNSS satellite signals. In some embodiments the attitude system computes first measured and second estimated carrier phase differences in order to detect the false GNSS satellite signals. The attitude system may compute the attitude of a baseline vector between the two antennas. Once false GNSS satellite signals are detected, the method can include preventing the attitude determining system from outputting position or location data.

    摘要: Systems and methods for providing a synthetic track to observation devices are provided. In one embodiment, a method can include determining a location range and a time range for a synthetic track to be created by a plurality of platforms. The method can further include determining an emission location and an emission time for each of the platforms of the plurality of platforms based, at least in part, on the location range and the time range. The method can include sending a set of data to each of the plurality of platforms, each respective set of data indicating the emission location and the emission time at which the respective platform is to generate the emission to create the synthetic track.
