Abstract: An OFDM communications system comprises broadcast providers 400, earth stations 100, repeater satellites 200, and receivers 300 (for example mobile receivers). The size of the multiplex can be increased by adding extra channels. Two channels are provided, on the in phase and quadrature components of each subcarrier.
