First Claim
1. A mobile transmitter-receiver (transceiver) system comprising:
- a first receiver and a first demodulator for receiving and demodulating a first video Orthogonal Frequency Division Multiplexed (OFDM) modulated signal into a first demodulated OFDM video baseband signal and providing said first video baseband signal to an interface of a mobile unit;
a first processor and a first transmit filter for processing and filtering a second video signal generated in said mobile unit and for providing a processed filtered spread spectrum second video baseband signal, said processed filtered spread spectrum second video baseband signal comprises cross-correlated in-phase and quadrature-phase baseband signals, said first video signal is a distinct signal from said second video signal;
a modulator and a transmitter for modulation and transmission of said second video cross-correlated baseband signals;
a second receiver and a second demodulator for receiving and demodulating a modulated signal into demodulated location finding baseband signal;
a converter for converting a photo camera generated signal into a baseband photo camera signal, said photo camera is in said mobile unit;
providing said location finding baseband signal with said baseband photo camera signal to said modulator and transmitter for modulation and transmission of said location finding baseband signal with said baseband photo camera signal in said mobile unit;
a touch screen generator for generating a touch screen signal, said touch screen signal is used for control of said mobile unit; and
a receiver for receiving a motion generated signal and using said motion generated signal for control of one or more functions of said mobile unit.
