  • Patent number: 7215954
    Abstract: A mobile wireless communications system including a plurality of individual transponding nodes of various types, all in communication with a central processing hub. A local user signal is processed by the central processing hub and radiated through multiple paths to a plurality of the plurality of individual transponding platforms simultaneously. The signal is then re-radiated by each of the plurality of the plurality of individual transponding platforms to a mobile terminal that receives the re-radiated signal from the plurality of the plurality of individual transponding platforms coherently and in phase. The number of transponders and codes used to transmit each user signal can be readily adapted to user requirements. Additionally, each user is assigned a profit value by the central processing hub depending upon certain user characteristics. The assigned user profit value allows the total system utility/profitability to be maximized.

  • Patent number: 6421532
    Abstract: The invention relates to a receiver system for vehicles having an antenna and a receiver with an interference signal receiving device. This interference receiving device comprises a coupling element with an input for taking up the pulse-like interference radiation emitted by the vehicle aggregates and which interference radiation emitted by the vehicle aggregates and which interfere with the reception, with an evaluation circuit for presenting the interference radiation. A controllable transmission element is disposed within the receiver between transmission elements. Controllable transmission element is controllable with respect to its transmission behavior for the purpose of signal sampling, which also receives output signals of evaluation circuit so that during the duration of the interference pulses, the interference pulses interfered with receive and sample usable signals.
