Abstract:
1. A system comprising: a first baseband circuit for receiving a baseband signal and for providing a spread spectrum baseband signal; a second baseband circuit for receiving a baseband signal and for providing a filtered baseband signal; a third baseband circuit for receiving a baseband signal and for providing cross-correlated in-phase and quadrature-phase baseband signals; baseband selector and connection device for selecting and connecting one or more of the spread spectrum, filtered or cross-correlated baseband signals to a transmitter; and a transmitter for transmitting the baseband signal connected to the transmitter wherein said transmitter comprises a linearized amplifier for transmission of the spread spectrum signal and a non-linear amplifier for transmission of the cross-correlated in-phase and quadrature-phase signals.
