ABSTRACT:
Modulators for switched or switched and combined Orthogonal Frequency Division Multiplexed (OFDM), Code Division Multiple Access (CDMA), Spread Spectrum, Time Division Multiple Access (TDMA), cross-correlated and filtered systems. A first modulation circuit for receiving input OFDM baseband signals and a second modulation circuit for receiving input in-phase and quadrature-phase cross-correlated baseband signals, TDMA signals, spread spectrum signals, CDMA signals or other filtered signals. One of the switched or combined modulated Radio Frequency (RF) signals and the other switched or combined modulated RF signals are provided to one or more selected transmitters.
