Abstract:
1. A wireless system comprising: a first baseband processor for receiving and processing signals and for generating from said signals Orthogonal Frequency Division Multiplexed (OFDM) baseband signals; a first modulator for receiving and modulating said OFDM baseband signals wherein, said modulator is a quadrature modulator; a second baseband processor for receiving and processing location finder information signals and analog to digital converted (ADC) voice signals and for generating combined location finder and ADC voice signals, wherein said second baseband processor comprises a cross-correlator and filters for generation of combined cross-correlated in-phase and quadrature-phase filtered baseband signals; a second modulator for receiving and modulating said combined cross-correlated in-phase and quadrature-phase filtered baseband signals, wherein said second modulator is a quadrature modulator; a first amplifier operated in a first radio frequency (RF) band in a linearly amplified (LINA) mode for receiving and for amplifying the modulated OFDM signals; a second amplifier operated in a second radio frequency (RF) band, wherein the second RF band is different from the first RF band in a non-linearly amplified (NLA) mode for receiving and for amplifying the modulated combined signals; and a selector for selecting either the first or the second amplifier amplified signals and for providing the selected signals to a signal transmitter for transmission of the selected signal.
