Abstract

A wireless system for receiving, processing and transmitting video, voice and location finder signals and for providing filtered cross-correlated in-phase and quadrature phase baseband signals and non-quadrature baseband signals for transmission. The cross-correlated in-phase and quadrature phase baseband signals include applications in Time Division Multiple Access (TDMA) and or Code Division Multiple Access (CDMA) systems. The transmitter system in certain applications includes a first and a second transmitter wherein the first transmitter is operated in a separate Radio Frequency (RF) band than the second transmitter while in some other implementations comprises a first and a second transmitter wherein the first transmitter is used in a linearly amplified mode and the second transmitter is used in a non-linearly amplified mode. In certain embodiments the location finder signals comprise signals received from satellite based and from non-satellite based location finder transmitters.
