1. A Multiple Input Multiple Output (MIMO) system comprising:

  • a interface unit for receiving signals received from multiple input receivers;

    a first processor and filter for processing and filtering received location finder signals and for providing location finder processed filtered baseband signals to a polar modulator for polar modulation of processed baseband signal, said polar modulated signal having a first modulation format;

    a second processor for processing received signals and for providing processed baseband signals to a non-quadrature or a quadrature modulator for modulation of processed baseband signal, said non-quadrature or quadrature modulated signal having a second modulation format;

    a third processor for processing received signals and for providing processed baseband signals to a Orthogonal Frequency Division Multiplex Access (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA) modulator for modulation of processed baseband signal, said OFDM or OFDMA modulated signal having a third modulation format, wherein the first, second and third modulation formats have distinct modulation formats;

    a selector for selecting and providing one or more modulated signals to a multiple output signal transmitter system;

    a multiple output signal transmitter system for transmission of one or more selected modulated signals, comprising two or more transmitters; and

    a receiver system comprising two receivers for reception and demodulation of the transmitted signal.
