Abstract:
1. An apparatus adapted to transmit a first channel on at least two adjacent beams of a first plurality of beams defining a coverage area, with each pair of adjacent beams of said first plurality of beams partially overlapping and having alternating polarizations; the apparatus comprising a respective transmitter adapted to transmit on each of said first plurality of beams a respective unique composite signal, each composite signal comprising said first channel and a respective at least one unique traffic channel; the apparatus being further adapted to receive over a second plurality of beams comprising a corresponding beam for each beam of said first plurality of beams which is substantially co-extensive with the beam of the first plurality of beams and has a respective polarization which is substantially orthogonal to the polarization of the beam of the first plurality of beams.
