Abstract
A method for communication includes, in a transmitter that transmits one or more data streams to respective target receivers and one or more jamming streams for preventing the data streams from being decoded by eavesdropping receivers, holding a definition of at least first and second transmission modes having respective, different first and second levels of security in preventing the data streams from being decoded by the eavesdropping receivers. One of the first and second transmission modes is selected for transmitting a data stream to a target receiver, by evaluating a selection criterion. The data stream and the jamming streams are transmitted via an antenna array using the selected transmission mode.
Claims22
A method for communication, comprising:
- in at least one transmitter that transmits one or more data streams to respective target receivers and one or more jamming streams for preventing the data streams from being decoded by eavesdropping receivers, holding a definition of at least first and second transmission modes having respective, different first and second levels of security in preventing the data streams from being decoded by the eavesdropping receivers;
- selecting one of the first and second transmission modes for transmitting a data stream to a target receiver by evaluating a selection criterion;
- and
- transmitting the data stream and the jamming streams via an antenna array using the selected transmission mode,
- wherein transmitting the data stream using the first transmission mode comprises transmitting at least one jamming stream simultaneously with the data stream, and wherein transmitting the data stream using the second transmission mode comprises transmitting the data stream while inhibiting transmission of the jamming streams.
A communication apparatus, comprising:
- transmission circuitry, which is configured to transmit data streams to target receivers and jamming streams for preventing the data streams from being decoded by eavesdropping receivers;
- and
- a control unit, which is configured to hold a definition of at least first and second transmission modes having respective, different first and second levels of security in preventing the data streams from being decoded by the eavesdropping receivers, to select one of the first and second transmission modes for transmitting a data stream to a target receiver by evaluating a selection criterion, and to control the transmission circuitry to transmit the data stream and the jamming streams via an antenna array using the selected transmission mode,
- wherein the control unit is configured to control the transmission circuitry to transmit at least one jamming stream simultaneously with the data stream in the first transmission mode, and to transmit the data stream while inhibiting transmission of the jamming streams in the second transmission mode.
