1. A method of phase conjugated vectoring (PCV) of transmission signals propagating via a plurality of twisted pairs of a telephone cable comprising the steps of:

  • propagating a reference signal from a receiver site via one twisted pair of said plurality for obtaining a wavefront of PCV reference signal at a transmitter site;

    establishing PCV antenna bundle for each twisted pair of said plurality;

    scaling input transmission signals by said PCV reference signal for obtaining mutually coherent PCV transmission signals; and

    propagating said mutually coherent PCV transmission signals via said PCV antenna bundles for receiving only one signal in a corresponding twisted pair at the receiver site.
