Multiple Input Multiple Output (MIMO) system for receiving signals received from multiple inputs and transmitting signals to multiple output signal transmitters and multiple receivers for receiving transmitted signals. Processor for processing received location finder signals and for providing location finder processed baseband signals to a polar modulator for polar modulation of processed baseband signal. Processors for providing processed baseband signals to a non-quadrature or a quadrature modulator for modulation of processed baseband signal. Processor for processing and providing Orthogonal Frequency Division Multiplex Access (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA) signals for modulation and to multiple output transmitters. Processor for processing received signals and for providing processed baseband signals to a cross-correlator for cross-correlating and filtering in-phase and quadrature-phase baseband signals and for providing cross-correlated quadrature signals to a quadrature modulator for modulation of cross-correlated filtered baseband signal. Spread spectrum processor and cross-correlator for spread spectrum processing and cross-correlating in-phase and quadrature-phase baseband signals. Time Division Multiple Access (TDMA), Global Mobile System (GSM) processors and baseband filters for providing TDMA, Bluetooth, spread spectrum and GSM system signals used in MIMO systems. Receiver system comprising two receivers for reception and demodulation of the transmitted signal.
