Claim Text:
1. A method for minimizing in an adaptive and decentralized manner fratricidal effects induced by jamming of P predefined zones ZB or positions in a communications network comprising friendly transmitters, jammers and friendly receivers, said network comprising N_pl platforms, a number M≦N_pl of said platforms, being friendly transmission platforms equipped with antennas and with systems for transmitting useful transmission signals configurable in a dynamic manner, a number N≦N_pl of said platforms, also being friendly, and being equipped with dynamically configurable antennas and systems for receiving useful transmission signals, a number J≦N_pl of said platforms being equipped with jamming systems and antennas having characteristics known to the friendly transmission and reception platforms, said jamming systems and antennas being adapted for preventing the transmissions between entities external to said network of friendly platforms, said platforms constituting a network, comprising at least the following steps: E E ascertaining a priori the waveforms of the jamming signals and the associated parametrizations, on the basis of the states of the local situations of jamming established by each of the N receiving platforms on the J signals originating from the J jammers, on the basis of a local reception situation established by each of the N receiving platforms on useful communication signals Su; determining for each of the M friendly transmitting platforms and for each of the N friendly receiving platforms, at least one of the following configuration parameters: a frequency plan, and/or temporal positionings of the transmissions, antenna diagrams and/or orientations, radio access schemes and modulation/coding schemes for the signals transmitted and received, the parameter or parameters being adapted for minimizing or eliminating the fratricidal effects on the N friendly reception platforms, using the said configuration parameters in transmission and/or reception for the M friendly transmission platforms and the N friendly reception platforms.
