1. A method for establishing a plurality of communication links to a plurality of user terminals comprising:

  • pre-processing a plurality of local user signals at a ground hub to compensate for differential propagation delays to any one of the plurality of user terminals;

    assigning each of said plurality of user terminals one or more resource cells in platform-code space at the ground hub;

    transmitting transmit signals to the hub through one or more of a plurality of individual transponding nodes using a first resource cell of the one or more resource cells;

    coherently receiving signals from more than one of the individual transponding nodes using a second resource cell of the one or more resource cells; and

    post-processing transmit signals at the ground hub to compensate for differential propagation delays such that all transmit signals from one of the plurality of user terminals may be coherently processed.
