Abstract:
1. A wireless communication system supporting orthogonal frequency division multiplexing (OFDM) having a base station comprising: a) a quadrature modulator adapted to generate symbols from data to be transmitted; b) a symbol encoder adapted to encode the symbols based on space and time wherein constellation position and timing of the symbols are affected to provide a plurality of series of encoded symbols; c) transform circuitry adapted to provide a type of inverse Fourier Transform (ITF) on each of the plurality of series of encoded symbols to provide a series of ITF symbols; and d) a plurality of transmission paths, each of which being coupled to one of a plurality of antennas and adapted to modulate one of the series of IFT symbols for transmission from one of the plurality of antennas to provide spatial diversity.
