Patent ID: 7415066

Claim:
A system comprising: a processor and transmit baseband filter for processing, filtering and providing a first modulation format signal and a second modulation format signal to a modulator and a transmitter for modulation and transmission of the processed filtered baseband signal, wherein first and second modulation formats are distinct modulation formats; a transmitter comprising a first radio frequency (RF) amplifier operated in a first RF band in a linear or a linearized mode for amplification of the first modulation format modulated signal and a second RF amplifier operated in a second RF band in a nonlinear or saturated mode for amplification of the second modulation format modulated signal, wherein first RF band is distinct from second RF band; a switch for selecting the first or the second modulation format signal and for providing the selected signal to said modulator for modulation and amplification and for providing the selected amplified signal to a transmission medium; a receiver for receiving the transmitted signal received from the transmission medium and for providing received signal to a demodulator; a demodulator and receive baseband filter for demodulation and filtering of the received signal, wherein the receive baseband filter is mis-matched to the transmit baseband filter; and a receive processor for receiving and processing demodulated baseband filtered signal and for providing a first and second format cross-correlated in-phase and quadrature-phase baseband signal.
