Abstract
Communication methods for receiving and demodulating in mobile devices signals from multiple locations and for providing baseband position finder signal. Providing in a first cross-correlator and filter cross-correlated in-phase and quadrature-phase filtered baseband signals from a digital input signal and in a second cross-correlator spread spectrum signals from a voice input signal. Providing Orthogonal Frequency Division Multiplex (OFDM) signal from a video input signal. Combining baseband position finder signal with one or more of cross-correlated in-phase and quadrature-phase filtered baseband signals, or cross-correlated in-phase and quadrature-phase spread spectrum baseband signals, or OFDM baseband signal, into a combined baseband signal and modulating and transmitting combined signal. Touch screen control signal for control of mobile devices.
