Abstract
A Global Positioning System (GPS), a touch screen generated signal, a first Orthogonal Frequency Division Multiplexed (OFDM) signal, a first Code Division Multiple Access (CDMA) signal and a first Time Division Multiple Access (TDMA) signal is received by two or more antennas and is processed into processed GPS, touch screen, OFDM, CDMA and TDMA signal and is provided to a subscriber unit-interface circuitry. The processed CDMA signal is a cross-correlated in-phase and quadrature-phase baseband signal. One or more of the processed GPS, touch screen, first OFDM, first CDMA or first TDMA baseband signal is provided for cascade processing, modulation and transmission into a second OFDM, second CDMA or second TDMA signal, wherein the second signal is distinct from the first signal. The transmitter has two or more antennas for transmission and linearly and a non-linearly amplified amplifier for linear and for non-linear amplification of modulated signals.
