Abstract:
1. A position finder and communication system comprising: a first processor for receiving and processing multiple signals received from multiple locations and for generating from said received signals a processed position finder signal; a second processor, comprising a first cross-correlator and a transmit baseband filter, for generating cross-correlated in-phase and quadrature-phase processed filtered baseband signals from an input signal; a third processor, comprising a spread spectrum processor and a second cross-correlator, for generating cross-correlated in-phase and quadrature-phase processed spread spectrum signals; a fourth processor comprising an orthogonal frequency division processor for generating a orthogonal frequency division processed signal; a fifth processor for generating a signal from a processing of the processed position finder signal generated by the first processor, with one or more of the signals generated by the second, third and fourth processors; a quadrature modulator for quadrature modulation of the signal generated by the fifth processor; and a transmitter for transmission of the quadrature modulated signal.
