1. A system comprising:

  • a first processor and filter for processing and filtering a spread spectrum signal and for providing a spread spectrum processed and filtered signal;

    a second processor for processing and filtering a Time Division Multiplexed (TDM) or Time Division Multiple Access (TDMA) signal and for providing a TDM or TDMA processed and filtered signal;

    a selector for selecting and connecting either the processed and filtered spread spectrum signal or the processed and filtered TDM signal or TDMA signal to a modulator system as a selected signal;

    the modulator system comprising one or more modulators for modulation of the selected signal and for providing the modulated signal to a signal transmitter for signal transmission,wherein the signal transmitter comprises two amplifiers, the first amplifier operated in a linearly amplified mode for transmission of the modulated signal from the spread spectrum signal and the second amplifier operated in a non-linearly amplified mode for transmission of the modulated signal from the TDM or TDMA signals.
