1. A method of spatially filtering spectrally overlapping communications signals, comprising the(a) receiving a plurality of radio frequency signals on an array of antennas;

  • (b) determining an optimum reception pattern for a signal of interest in said received signals as said received signals impinge on said array of antennas by restoring the spectral self-coherence of said signal of interest, said signal of interest corresponding to communications from a specified user; and

    (c) transmitting a signal to said user, said transmitted signal having a radiation pattern from said array of antennas substantially identical to said reception pattern of said signal of interest.
